Hilary Duff

Aaron Carter, who?

That's the response now of two of Hollywood's most famous young females, each of whom dated the boy band singer for reasons unknown.

At club Les Deux over the weekend, witnesses spotted Lindsay Lohan hugging it out with former rival, Hilary Duff. The source of their feud had been the younger Carter brother.

The bad blood began long before Lohan started doing James Blunt and every other guy in California:

In 2005, Carter appeared on the talk show The Big Idea With Donny Deutsch and told the host:

"I started dating Hilary on my 13th birthday... I was dating her for like a year-and-a-half and then I just got a little bored so I went and I started getting to know Lindsay, dating Lindsay."

Yes, Aaron the entire free world understands what "getting to know" Lindsay means. Brody Jenner certain does, at least.

At the club, though, the girls got reacquainted and found someone else to scorn: Paris Hilton.

A source told Us Weekly, "They were making fun of Paris!"

This makes them very different than anyone at The Hollywood Gossip, of course.

Meanwhile, Aaron Carter has finally moved on from this pair. He's completely in love with Kaci Brown.

Watching Sanjaya Malakar on American Idol is awkward.

Running into your ex on national TV? That's downright excruciating. Unfortunately, such a fate recently fell upon Hilary Duff.

"I just did TRL today and [Joel Madden] was there, and it was the first time we'd seen each other and it was so, like, nerve-racking," Duff, 19, told People magazine Monday at the 18th annual GLAAD Media Awards in New York City. "I knew that he was going to be there and he knew. It is what it is."

Showing maturity for her age, Duff said "it's life" when asked more about the encounter. She then said "it's slutty" when asked about her current wardrobe.

Since their breakup, Madden has been dating Nicole Richie, whule Duff has been single (something she's called "kind of exciting").

Nevertheless, Duff told the non-gay Ryan Seacrest in January that she and her ex keep in touch and have "a great relationship."

But was their run-in awkward? "It was a little strange at first, but I wish nothing but good for him and I know that he wishes the same for me," Duff said. "I'm happy and he's happy and I think that's all that counts."

Well, that and whatever the next round at Hyde will be.

When Hilary Duff lost a noticeable amount of weight two years ago, she chalked it up to healthier eating habits.

But now, the 19-year-old singer-actress admits she felt pressure not just from stalkers - but from the media. To get thin.

"I did get skinny," she tells Britain's Mail on Sunday.

So did Nicole Richie. Maybe you've noticed?

"I've felt pressure like everyone else in my position," said Hilary Duff, who likes to get her drink on at Hyde. "When a newspaper comes out that says 'Duff Puff â€" she must have gained 15 pounds' or something like that, how would any normal person react?"

THG NOTE: We'd probably tweak, unleash rage upon photographers, go to a barbershop and leave with a shaved head, then check into rehab.

She continues: "It's so mean, but everyone keeps buying that stuff and talking about it, so it's not going to go away."

Duff, whose two-and-a-half year relationship with rocker Joel Madden ended in November, tells the magazine:

"I felt like we were great together, and being on my own is great too."

After a trip to Europe to promote her new album, Dignity, Duff is now back home with her sister Haylie Duff, 22.

The two live together in Los Angeles in a house they shared until recently with their mom, Susan - who just moved down the street, much to her younger daughter's chagrin.

"It was her idea," says Duff.

"She said, 'I want to give you guys more freedom,' and I'm like, 'I don't want that. I want you here.' So I call her every day and I still always consult her before any big decision."

Think Lindsay says things like that to Michael Lohan?

Looks like that sighting of Hilary Duff drunk was a sign of things to come.

Sadly, it's getting hard to remember the days when Duff was the anti-Lindsay Lohan, that innocent virgin who chose baggy sweaters over revealing mini-skirts.

Even since she was tossed to the curb by Joel Madden, Hilary's outfits have become darker and tighter. We guess the singer is going through her gothic porn star phase, but we hope it doesn't last too long.

After all, the world needs a young artist that is known more for her songs and humanitarian efforts than her sexy outfits. For now, though, here are pictures of Duff at a recent concert, as she makes Kim Kardashian photos look conservative by comparison.

Hilary Duff is a charitable, wholesome actress.

But that doesn't mean the 19-year can't get down with her drunken self from time to time.

Reportedly, January 25 was one of those times. Hilary and older sister Haylie showed up - where else? - at L.A. club Hyde with a huge entourage.

The younger Duff - who has been single since splitting in November from Good Charlotte rocker Joel Madden arrived arm-in-arm with her sister after 11 p.m., looking tipsy already.

Soon enough, Hilary was teetering over to the women's restroom with one of her girlfriends, in a very vomit-ous state. Perhaps she was trying to drink away the pain of Madden hooking up with Nicole Richie.

"It was kind of inappropriate," a witness said. "She was pretty drunk and staggering around the bathroom, bumping into people and shrieking that her gay male friend had a vagina so it was okay for him to be there."

The sisters continued to party Britney Spears-style throughout the night at a VIP table, where sources say they were "all over" their two man-dates. Haylie 21, whispered in the ear of her 30-ish-year-old date while kissing his neck.

Hilary perched on her date's lap, laughing and flirting with her unidentified older man.

We can't say for sure who it was - but does anyone know where Kevin Federline was that night?

Hilary Duff must be in the forgiving, holiday mood.

Despite a difficult break-up with Joel Madden, the pair has found common ground in letting one dude who stalked them skate free from a restraining order.

TMZ obtained documents filed Monday in Los Angeles County Superior Court by the star duo's lawyers, which requests a dismissal of the restraining orders against celebrity photographer David Joseph Klein.

In October, Duff and Madden filed temporary restraining orders against Klein and his roommate Maksim Miakovsky, an 18-year-old Russian emigre.

The former couple feared for their safety and requested that a judge order the alleged stalkers to stay at least 100 yards away from Duff, her sister Haylie, Madden and his twin brother Benji.

Of course, now that Madden is dating Nicole Richie, future stalkers will probably be glad to stay away, lest they wish to get run over by a pill-popping bad driver.

This wasn't always the case. Hilary Duff used to be a happy-go-lucky child star.

She pitched in for charity. She hated being stalked. She dyed her hair. Good times were had by all.

But times have grown gruff for Duff. Not only did she break up with Joel Madden, she's been forced to watch him snuggle up to an flimsy waif with a vicotin addiction.

Indeed, Madden is now dating Nicole Richie. If he can find her, that is (that was an anorexic joke). You'd look as glum as Hilary appears in this picture, too, if you lost your man to a girl that weighs less than many newborns.

But keep that chin up, Hilary. At least you're not Janice Dickinson.

The good news for Hilary Duff is that she no longer has a stalker (and, apparently, Bob Uecker never did; just for the record).

The bad news is that the young singer/actress also doesn't have a boyfriend.

Duff and Joel Madden are no longer dating, as confirmed by Madden during a guest DJ appearance at a club in Chicago over the weekend. The rocker talked about being single, telling clubgoers that Duff had broken up with him ten days earlier.

The reason? We doubt it was Duff's new goth look, although if you see her dating either of the Olsen Twins, now you'll know why.

In reality, it was Duff and Madden's age difference (he's 27, she's 19) that caused problems. Sadly, this doesn't bode well for Wilmer Valderrama and Ali Lohan.

While we were focusing on a possible new look for Hilary Duff, policemen were patrolling the streets, on the lookout for her supposed stalker.

It paid off. The 18-year-old who allegedly threatened to kill one of our favorite young singers has been arrested.

Manhattan Beach cops arrested Maksim Miakovsky, an 18-year-old Russian emigre, at a Residence Inn last week. He was booked on charges of making criminal threats and stalking.

There was no word on whether or not a bitter Lindsay Lohan hired the thug out of jealousy of Duff's clean reputation.

TMZ first reported last month that Duff and her boyfriend, Joel Madden, were terrified that Miakovsky would cause them hard. Duff and Madden asked for a restraining order, alleging that Miakovsky "has stated his intention of 'removing' his 'enemies' (i.e., those who prevent him from being with her), has stated his intention of purchasing a weapon, and has threatened to kill himself and to engage in dramatic actions to get her attention."

Pretty much makes Tom Cruise and Katie Holmes appear sane.

Sources said a private investigator from Sunset Protective Services contacted Miakovsky at the Residence Inn and Miakovsky stated his intention of killing Duff on Sunday at an event she was scheduled to attend.

According to legal papers filed by Duff, Miakovsky came to the U.S. "for the sole purpose of meeting and becoming romantically involved with Ms. Duff."

Miakovsky is currently being held on $200,000 bail at the Manhattan Beach jail. He's scheduled to be arraigned on Tuesday. We hope he either goes to jail for a long time or is forced to stalk Stavros Niarchos from now on.

What is Hilary Duff thinking?

Has she been inspired by all the other newfound brunettes out there on the Hollywood scene (Cameron Diaz, Lindsay Lohan and even new mom Britney Spears come to mind), or by her punk rocker boyfriend, Joel Madden? Or is it for a new role? In any case, Duff is looking rough... although we may warm to it.

The formerly blonde star darkened her locks to a light auburn shade earlier this year, drawing generally positive reviews from T.H. Gossip (before we asked if we could touch it and her people served us with a court order to quit stalking her).

But last weekend, Duff turned up at the Carousel of Hope Ball in Beverly Hills with dark, almost-black hair. While it's a little disconcerting to see our little Barbie girl / Lizzie McGuire go goth, we think the dark color really brings out Hilary's hazel eyes and porcelain skin. But that's just us. We take celebrity fashion very, very seriously.

T.H. Gossip asks you, fans: How do you like your Duff?
