What's the best part about Super Bowl Sunday? For bookies, bartenders and football fans, it's all about the big game (duh). For the rest of us, it's some combination of outré ads and extra cheesy bean dip. But for a whole lotta celebs -- like LL Cool J, Kevin Connolly and Nick Lachey -- the Super Bowl's all about the party circuit. And at this year's Maxim bash (Saturday night, in Miami), no one made a bigger splash than the cast of The Hills.

So what made their entrance so killer? Well, in addition to looking gorge on the red carpet (as usual!), the girls turned heads by putting their past awkwardness aside and laughing it up like a bunch of old friends. Case in point? Kristin Cavallari, who smiled gamely while throwing her arms around one-time nemesis Audrina Patridge!

+ Think this means 'Drina and Kristin have finally turned a corner (and quit fighting over Justin Bobby)? We're not sure, but for now, we're just enjoying the peace n' quiet! Anyhow, check out these shots of Audristin(!) posing with Lo, Steph, Brody and Frankie Sat night, then let us know if you think they're done feudin' for real.

Lauren Conrad is glowing on the March cover of Seventeen magazine, but it's the story inside that's attracting all the attention. In between promoting her new book (and discussing what first attracted her to reality TV), LC is shocking readers with a startling confession: one of her ex-boyfriends on The Hills was a two-timing cheat!

"Oh, I knew back then when I was being cheated on," she told Seventeen. "But I overlooked it. The more confident me has come to the point where I’ve finally realized it’s not something that everyone does. And it’s not okay to have your guy hook up with someone else. You deserve better."

Obvs, we're glad to hear LC's moved onwards and upwards (to devoted bf/practicing monogamist Kyle Howard), but we can't help but wonder: which former Hills-era squeeze had the wandering eye? We've rounded up a list of the usual suspects, so take the poll and tell us who you think did the dastardly deed!

Happy birfday, Lauren Conrad! It's the big 2-4
So we've written you a poem (but, oh wait! there's more!)
We've also put together a short (rhyming!) list
Of our fave LC memories. Like that first Brody kiss!

Or the days when you and Whitney sat side by side
In a Teen Vogue cubicle, about eight feet wide
(When you believed so strongly in summer romance
That you became The Girl Who Didn't Go To France)

There were She-Pratts and Speidis and trips to Sin City
New puppies and hypoallergenic kitties
Catfights, boy dramas and one big Jen Bunney mess
Three different roomies, one (badly burned) couture dress

From the time Heidi crashed your first Teen Vogue party
To the time Spencer FINALLY said he was sorry
Thanks for all the amazing Hills memories
Happy happy! From all of us here at RC.

We already told ya about Stephanie Pratt's Everybody Sundance Now phase, and showed you an excerpt from Lauren Conrad's candy-coated new book. So what's been happening elsewhere in Hillsville? Well, Spencer Pratt's been getting his meditation on with "The Rock" (no relationship to Dwayne Johnson) while Heidi's been looking to her crystal ball Chinese takeout for answers (pssst, they're right there, next to the duck sauce!). Read on for our Hills Twitter Roundup and find out why Audrina's parents deserve a medal, Steph Pratt deserves a round of applause and LC deserves really wants a snack.

+ You know what they say: there's no place like "ohm". Check out this Twitpic of Spencer and his 1500-pound pal's big reunion!

It's not the first time Jayde Nicole and Brody Jenner have called things off -- but when the couple decided to quit each other (again) last month, something told us this latest breakup might be their last. So what went wrong? We're not sure about the final nail in the coffin, but Jayde says one thing's for sure: having the world constantly judge her romantic life didn't help. "Its hard [having everybody] watching your relationship and kind of scrutinizing it," Jayde told OK! magazine.

With all that drama hanging over her head, Jayde said she's not sure whether she'll be returning for Season 6 ("As of right now, I’m not going to be on the show,” she said), but explained that she's still been in contact with some of her costars -- including Brody.

"Me and Brody still keep in touch," Jayde told OK!. "We’re still friends. Everyone that I was friends with on the show I’m still friends with now.”

Seriously, it's not like Jayde's been sitting at home, reading about Brody and Whit in the tabloids and waiting for her phone to ring. Check out these pix of her getting cozy with Entourage star Adrian Grenier at a poker tourney last week. Jealous much, Brody?

As soon as rumors of Whitney and Brody's (supposed) hookup hit the web, everyone had one thing on their minds: What would Lauren Conrad think? True, she hasn't dated Brody for years (and has happily moved on to My Boys star Kyle Howard), but as Whitney's close, personal friend and Brody's ex-turned-confidante, LC's got two options: wave this off -- or see it as one big (and extremely public) betrayal. So how will she react? Assuming Whit and Brody ARE the real deal, does LC have the right to be pissed? Take the poll!

Rumor has it, Hills hunk Brody Jenner (who split with Jayde Nicole last month) is already back to playing the field. The newly single reality star was spotted canoodling with a leggy blonde last weekend -- and, no, the lucky gal wasn't Kristin Cavallari ... it was City star/Hills alumnus Whitney Port! Yep, sources told the New York Daily News that Whit "couldn't keep her eyes" off the Brodester and said the cozy duo was practically joined at the hip.

"They didn't come together, but Whitney ran over to see him the second he walked in," said the NYDN's eyewitness, who added that the former costars "stayed together for much of the evening" before leaving the club together.

So does this mean Whitney and Brody are more than just friends? We're not sure, but we're betting Lauren Conrad (ahem, Brody's one-time gf) would love to find out. FYI, LC has yet to say a word about the latest fling rumors, but she HAS warned Whit against dating Brody in the past. Check out what LC told Whitney about steering clear of the Brodester in this "lost" scene from The Hills: Season 3.

The first week of 2010 was a busy one for the Hillzies. Stephanie Pratt tweeted about everything from her love for Lo Bosworth to her lust for Robert Pattinson, while Lo Bos made the resolution to end all resolutions. Meanwhile, a freshly vacationed Lauren Conrad hit the gym, Brody Jenner hit the sack and Heidi Pratt hit up Paris Hilton and Nicole Richie. Find out what else went down on this week's all-Hills edition of the MTV Twitter roundup!

Happy birthday, Kristin Cavallari!
You always were the life of the party

And in honor of your special day
We thought we'd recount all the ways
You make our lives so cheery and bright
By bringing the drama to Tuesday nights

Thanks for bustin' out the girl-on-girl kisses
For starting a catfight with Brody's missus
For proving Justin Bobby is so much more
Than a greasy biker (and monosyllabic bore)

For bringing Stacie the Bartender back into our life
For introducing Spencer Pratt to his lovely wife
For throwing down with 'Drina at Casa de Speidi
For getting more action than Aphrodite

Kristin, we love you, and we wish you the best
Here's to life, love and happiness -- and all your success

Oh, what a year. In 2009, we said goodbye to Lauren Conrad, hello (again) to Kristin Cavallari and learned that Speidi's not quite ready for an Enzo of their own. Along the way, we saw Brody and Jayde fight, make up and call it quits (for good!?), watched Audrina Patridge stick it to her ex and stared on in disbelief as Kristin and Justin snuggled under the sunset.

So what's in store for the year ahead? Well, unlike Kelly Cutrone, we can't predict the future, but we CAN tap into your brains to find out who thinks K-Cav and JB will still be going strong come spring. Will this rocky romance survive another season? Take the poll and tell us whether you think Kristin Bobby will stay together in 2010.
