High School Musical co-stars Vanessa Hudgens and Ashley Tisdale proved two things during their shopping spree in L.A. this week:

1. They may not hate each other after all.
2. They can appear in pictures with their clothes on.

But the real question, of course, is: Which young star looks better? Here's a quick look at what the respective girlfriends of Zac Efron and Jared Murillo are sporting...

Hudgens is wearing a basic white shirt with a silk scarf tied around her neck and the ultimate accessory on celebrity divas: over-sized sunglasses.

Tisdale, meanwhile, is going for the rocker chic look in her skinny black jeans, trendy oxford booties and Chanel sunglasses.

You tell us, celebrity gossip fans: Who looks better?

Christina Aguilera, who?

There's a new Queen of Dirrrty - and it's... Oprah Winfrey?!?

No, seriously, check it out:

What hole? We don't get it. Maybe Karrine Steffans can explain it to us.

For those of you complaining that 100 percent of our Hayden news is focused on Heroes' Hayden Panettiere ... here's a Hayden Christensen sighting!

This handsome young actor, best known for completely butchering the legendary character of portraying Anakin Skywalker in Star Wars: Revenge of the Sith, is seen here getting into a hot hybrid Lexus on Wednesday in Los Angeles.

The Lexus might not be the only ride Hayden Christensen takes today.

The owner of said car? None other than Rachel Bilson, who he's been dating for awhile now! You don't hear a lot about this couple in the media.

Besides his hellacious acting ability, we don't know why. She's really cute at least! Then again, she's not exactly a media whore. Talking to you, Heidi Montag.

Come on. Who do you think she is?

• Paris Hilton?
• Britney Spears?
• Lindsay Lohan?

She's not. Hayden Panettiere has some actual talent - not to mention brains when it comes to handling the invasive celebrity news media.

For the second consecutive day, the Heroes starlet managed to thwart a potential upskirt / crotch shot from the eager paparazzi as she exited a vehicle on her press tour. All we got to see on Larry King Live was her pretty face. That's a good thing.

Denied! Hayden Panettiere nixes another crotch shot.

Your score, after two days: Hayden Panettiere 2, Paparazzi 0. Photographers hoping for a Hayden Panettiere upskirt shot might as well quit trying now.

The girl can't even buy beer. She's not going to get drunk and let her guard down. As for what co-star Milo Ventimiglia sees behind closed doors, that's another story.

You've missed celebrity gossip updates about Lindsay Lohan, haven't you?

Go on, admit that you can't stand this booze hound of a skank... yet also can't wait to see what she'll do next.

According to her evil mother, Dina Lohan, here's the answer: nothing. Contrary to reports stating otherwise, the Firecrotch Queen will not be leaving the Cirque Lodge rehab program in Utah this weekend.

People magazine reports that Dina emailed Access Hollywood this week with the breaking news that her daughter is "staying in Utah."

For those that think Kiefer Suhterland is the first star to drive drunk, don't forget: Lindsay's treatment at the facility began last month, following her early morning July 24 arrest in Santa Monica on suspicion of DUI after a brief car chase.

From there, a small amount of cocaine was found on the ex-sexual partner of (deep breath now...) Calum Best, Harry Morton, Jude Law, Criss Angel, AJ Lamas, James Blunt and many others.

Immediately after she was booked, her attorney blabbered on about how Lohan had "relapsed" and was receiving "medical care."

Michael Vick is totally becoming a chew toy ... literally (for dogs) and figuratively (for the legal system)! The problems just keep piling on!

The Atlanta Journal-Constitution has obtained court documents that indicate the embattled NFL star tested positive for marijuana September 13, and will now face even more strict release conditions from a federal court judge.

In court documents yesterday, the judge ordered Michael Vick to submit to drug testing, "for determining whether the defendant is using a prohibited substance."

The judge also ordered Vick to stay in his Virginia home - with electronic ankle monitoring - every day from 10:00 p.m. to 6:00 a.m. No Les Deux for you, #7! Moreover, he has to foot the bill for the service. It's a dog-eat-dog world, no?

ABOVE: A stressed out Michael Vick looks to roll a joint at a press conference following a tough Falcons loss. It's tough running an NFL offense and a dogfighting ring.

In addition, Vick has been ordered to attend a substance therapy program and get mental health counseling. Vick will be sentenced to prison time on December 10, after entering a guilty plea in federal court on charges related to dogfighting.

He faces up to five years in prison. The State of Virginia is also filing new charges against Vick, though his lawyers contend that legally, he can not be convicted for the same heinous, ridiculous, stupid crimes twice.

If anyone needs a break from Hollywood right now, it's Britney Spears.

But if anyone else could use a bit of rest and relaxation, it's Kristen Bell.

The former star of Veronica Mars is involved in numerous projects at the moment. She deserves the bikini-clad break it looks like she's taken below.

Move over, Kristin Cavallari and your bikini. Another Kristen has something to say about looking good in a bathing suit.

Here's a review of what Bell has been up to:

• She recently completed filming on Forgetting Sarah Marshall, a movie title worth remembering when it hits the theaters in the spring. How come? Because it's the next, hilarious Seth Rogan film.

• She's the voice of Gossip Girl in, well, Gossip Girl. That CW show is picking up a cult following.

• She'll be guest starring on the series Heroes, beginning in a few weeks. Perhaps you've heard of that NBC drama.

So, take a load off, Kristen. We can't wait to hear and see more from you.

We know Britney Spears is perhaps the most famous public restroom user ever - who doesn't use the can at Quizno's while celebrity news photographers crowd outside?

Yet this week, the train wreck took it a step further, not only stopping to use the toilet at a public place, but inviting a member of the celebrity gossip media into the ladies' room with her, and reportedly, asking for help procuring a tampon. Amazing.

We're worried about Matthew McConaughey.

The care free bachelor who rarely wears a shirt is seen below... completely dressed AND escorting his beautiful girlfriend, Camila Alves, into a car.

Might this be the end of the topless, bed hopping McConaughey we've grown to love?

Meanwhile, Sarah Larson appears to have tamed George Clooney. What's happening to all the hot bachelors of the world?

It's a good thing we still have Brad Womack.

Don't worry, Karrine Steffans, we haven't forgotten about you.

The woman behind "Confessions of a Video Vixen," hasn't been heard from in awhile. After all, she hasn't broken up Bobby Brown and Whitney Houston's marriage in months.

But the video music star/dancer has a new book out, one chock full of salacious new stories of her (numerous) sexy romps.

"The Vixen Diaries" is billed as a self-help book for some reason. But it still mentions her naked time with actors and musicians such Jamie Foxx, Bobby Brown and Bill Maher.

Moreover, Steffans assures readers she did not break up the unions of Brown and Houston... or Halle Berry and Eric Benet... or Chris Rock and Malaak Rock. She doesn't exactly explain just why these endless rumors began in the first place, however.

In closing, Karrine dedicated to book to Maher, who she refers to as "the love of my life." And Lord knows she's had many to choose from.
