Lauren Bosworth

A trio of cuties from The Hills - Lauren Conrad, Whitney Port and Lauren "Lo" Bosworth - posed for pictures at the A Time for Heroes Celebrity Carnival at the Wadsworth Theater in Los Angeles on Sunday night ...

Lauren, Lauren and Whitney: The Hills stars out in full force!

Needless to say, our favorite girls all looked terrific at the event. Click to enlarge more photos of LC, Lo and Whitney Port below ...

For best friends Lauren Bosworth and Lauren Conrad, it was a case of the blonde leading the blind - or, in this case, the blonde - Thursday evening at the opening of Strike Orange County in Tustin, Calif...

Blonde trust: Lauren Bosworth guides Lauren Conrad.

In spite of their admittedly poor bowling skills, Lo Bosworth and Lauren Conrad tackled this sporting task - but focused on the most important things.

"I've never scored above 100 ever. I normally get, like, around 60," said Lo, bowling with martini in hand, of course.

At a private hilltop location in L.A., The Hills cast and their fans on Monday celebrated the Season Three finale with a blow-out party Monday.

While it was sad to see Season 3 come to an end, there's a whole new year of drama to look forward to in Season 4, beginning in late summer.

Here's a look at what's next for Lauren, Lo, Audrina and others, via some hot spoilers and gossip TV Guide unearthed at the party ...

Boys, Boys, Boys

Expect more, more, more. Lo and Lauren throw a big party in their new pad and invite boys galore. The ever-single Stephanie Pratt feasts her eyes on, well, everyone, and Lauren Conrad may have a new beau (Doug Reinhardt?) in tow. And as for Audrina and Justin Bobby? They're definitely back on. As Audrina herself says, "[Justin] has always been there for me, and he still is."

Friends in Lo Places

As far as Lauren Bosworth (Lo) is concerned, the tension has little to do with her - despite a self-described "foul face" when the topic comes up.

Next season, expect more from Lo's perspective.

"It's disheartening to see me turn into such a bad guy on the show," she said. In Season Four, "You're going to see the other side of the story. I think people need to remember that it's Audrina and Lauren's relationship that's having problems.... It's not my relationship to muck up."

The third season finale of The Hills begins with Heidi Montag in Las Vegas with Brent Bolthouse and Sam Nazarian, her bosses. In L.A., Spencer Pratt sulks as usual - but then decides he's gonna put it all on the table.

"We're going to Vegas!" he tells sister Stephanie Pratt.

They hop in the car and five hours later, they're in Sin City. Stephanie plays the role of clandestinely finding out where Heidi is. Then Spencer sneaks up on her as she sips cocktails at some swanky joint with her bosses.

Mortified, she leaves the table and we are treated to an epic Heidi and Spencer fight. But this time he is more reserved. Determined, he says that "We need to be together ... just come back to L.A. with me."

Heidi Montag was conflicted, but apparently couldn't resist Spencer Pratt.

She stands up Bolthouse, pulling a no-show for their next big meeting, and is next seen leaving her Vegas hotel with Spencer and Stephanie.

Back at Chateau de Lauren Conrad, Audrina Patridge is ... not there.

Ever since Lauren Bosworth (Lo) moved in with Lauren Conrad (LC) and her friend Audrina Patridge, things haven't been free of drama at Casa Conrad.

Audrina, who lives in the guest house while Lo and LC reside in the main residence of her Hollywood villa, is clearly feeling ostracized lately. Why?

On Monday's episode of The Hills, Lauren Conrad wanted to hang with Audrina at the recording studio where she works, but two seconds after they got there, Lo insisted they bail and go to dinner - sans Audrina - and so they did.

Many awkward moments and passive-aggressive comments from Lo soon followed - such as stating that their new puppy has TWO moms. Is she overprotective of Conrad? Jealous of Patridge? Are either or both out of line?

Tell us, which side are you on? Team Lo or Team Audrina?

Home may be where the heart is, but things aren't altogether sweet in the home of Lauren Conrad (LC) on this episode of The Hills.

Roommates Lauren Bosworth (Lo) and Audrina Patridge aren't really jiving, and the tension between them is getting worse by the minute.

While LC and Lo want to go tanning and shopping, Audrina has to go to Epic Records' studio, where the band Alkaline Trio is recording, for work.

She really wants the Laurens to stop by and see her, and they do, for about 15 seconds, before Lo complains about being hungry and they bail.

Lo denies any sort of blame by saying she's "just not cool enough to hang with bands," but Lauren Conrad is sad that her roomies haven't bonded.

If you thought Audrina Patridge's life was complicated, it pales in comparison to the reality show's other protagonist, the plastic-surgery loving Heidi Montag.

The fake-looking, duck-lipped bimbo decides that she wants to take her career to the next level. Her boss, club promoter / owner Brent Bolthouse, taps Heidi to help launch his new Hyde club - in Las Vegas! HOT!

Monday night's all-new episode of The Hills provided some seriously awkward moments - even by the MTV reality show's lofty standards.

It was supposed to be a regular night out in Hollywood - but everyone goes to Goa on Thursdays, remember. Lauren Conrad should have known better.

When LC got up a drink, she surely wasn't expecting her two least favorite people to have invaded her table when she came to sit back down ...

Justin-Bobby Brescia and Heidi Montag both happened to be at the club - and came over to see Audrina Patridge (who arrived with roommate LC) at almost exactly the same time. Awkwardness is a way of life on The Hills.

When Lauren Conrad returned from the bar and saw her least favorite life forms both chatting up Audrina, she sat at the other end of the table, acting like a bit of a drama queen and bitching to Stephanie Pratt about the suckiness of it all.

It was so painful to watch, yet we couldn't look away. Ah, The Hills.

Eventually, LC decided she couldn't deal anymore and made a break for it, grabbing trusty sidekick Lauren Bosworth (Lo) in the process. WTF.

Heidi Montag is determined to have a good girls' night out.

Even after Stephanie Pratt reveals that Lauren Conrad could show up at the same club, Goa (like, EVERYbody goes to Goa on Thursdays, OMG).

Heidi is undeterred by the LC factor, musing to Stephanie Pratt that "Maybe this will be the first time it's okay because I feel like she always had a problem with me because of Spencer and now that I'm not really with him... " Sure thing, girl.

At Goa, Heidi spots none other than Justin-Bobby (aka Justin Brescia), and goes to go warn Audrina Patridge about her dirtball ex's presence.

When Lauren Conrad goes to get a drink, Heidi makes her move, deftly avoiding LC and seeing Audrina. Justin-Bobby makes his way over as well.

When LC returns, two of her least favorite people are at her table. W... T... F. She says nothing to either of them directly, but is clearly far from pleased ... this was definitely one of the more awkward scenes in The Hills history.

"Oh my God, I have to leave this table immediately," she declares before grabbing BFF Lauren Bosworth (Lo) and bolting for the Goa doors.

The next day, Audrina Patridge meets up with Justin-Bobby Brescia one-on-one for conversation and drinks. He's a little bit more clean-cut than last season, while mumbling less, but come on, it's still Justin-Bobby. What a loser.

Days later, Heidi Montag goes to Stephanie's condo, only to find the great Spencer Pratt home alone, lounging around as usual. What does he even do in life?

Heidi, who honestly looks like more like a streetwalking hooker in each episode of The Hills, tells him about that night. Spencer doesn't care.

"I know you want to vent about this," the always-honest Spencer Pratt says to her, "but I really have no sympathy for you." SNAP!

As Heidi leaves, Spencer keeps jabbing at her:

"It was great seeing you. Enjoy your space."

Amazing. Finally, Lauren and Lo discuss moving and "getting a house" (code for somehow throwing down $2 million for an L.A. mansion) together. They debate whether or not they should invite Audrina to move in too. They seem torn.

Also torn? Audrina herself. While it seems that neither Audrina, nor LC and Lo, want Audrina to move in with them, she says she's in! Yay... we guess.

Fashion designer and star of The Hills Lauren Conrad arrives at the Us Weekly Hot Hollywood Hottest Style Makers Party in Hollywood on Thursday night.

LC spent a good deal of her time hanging out and having a good time talking with the press on the red carpet outside, but we realize you don't care. Like all of us, you just want to see beautiful Lauren Conrad photos. So here you go!

LC stayed close to Lauren Bosworth at the bash â€" at point she told her, "Don't lose me!" â€" but she also had some face time with another pal, Stephanie Pratt.

Where were Heidi Montag and Stephanie's brother, Spencer Pratt?

"I think they missed their flight," Steph said. "I was going to come with them!"

Here's LC, Lo and Stephanie Pratt at the event ...

Two more episodes of The Hills last night, one birthday party (Lauren Conrad), one career girl on the rise (Whitney Port) and one epic family feud (Spencer Pratt and Stephanie Pratt) that continues to escalate. Let's recap all the action ...

It's Lauren Conrad's birthday and, to celebrate, she invites her friends out to a club (called S Bar) - including Spencer's sister, Stephanie.

In the meantime, Spencer moves some strange, ugly-ass piece of furniture out of Heidi's apartment and into the middle of Stephanie Pratt's living room.

Anyone have any clue what that thing even is? In any case, she's livid and he's being a brat. This seems like a very real scene of sibling bickering.

At S Bar, BFFs Audrina Patridge, Whitney Port and Lauren Bosworth (Lo) dance the night away to ring in Lauren's birthday party. Stephanie then shows up with a friend, Roxy, and Lo and Audrina are skeptics, thinkin' she's up to something.

Stephanie Pratt is now in the middle of the Lauren Conrad-Heidi Montag feud.

The next day, Lauren and Brody Jenner meet for lunch and he ex-boyfriend, too, says LC should not be trusting Stephanie Pratt as, like, her new BFF.

Meanwhile, it turns out that Brent Bolthouse owns S Bar. Put that together? For you Hills newbies, a co-worker of Heidi Montag's was working the door at LC's party and, well, the cat's out of the bag that Stephanie went to the shindig.

Spencer confronts her and drives her to tears. This exchange follows:

Stephanie Pratt: "You're making me cry right now."
Spencer Pratt: "You're making YOURSELF cry, thinking about what YOU did."

Amazing. Later, Heidi Montag also reams poor Steph out.
