Audrina Patridge might've lost Justin Bobby to boyfriend stealer borrower Kristin Cavallari, but rumor has it she's already moved onwards (and, some might say, upwards) to mohawked Glee star Mark Salling. So how official is this supposed coupling?

Well, so far, all we've got to go on are UsMagazine.com's reports that the two were "talking into one another's ear and laughing" at Wednesday night's Hot Hollywood party (psst, we think it's called "conversing") before "heading off into the night together."

Hmm. We've seen a million alleged celeb "relationships" turn out to be nothing more than a glorified rumor (ahem, ahem, K-Cav and John Mayer). Plus, y'know, there's the whole "We Want Him For Ourselves" factor. But we'd hate to let our petty jealousy -- er, skepticism! -- get in the way of running an "Are-they-a-cute-couple?" poll. So, here it is! Now make with the superficial snap judgments and tell us whether this rumored relationship has you feeling all kindsa Glee-ful.

Well, now that Brody Jenner's back with Jayde Nicole (and Kristin Cavallari's back to being single), it's time for K-Cav and Stacie to get outta this two-boy town -- and spend a drama-free weekend in Vegas, baby! At least, that WAS the plan ... 'til Justin Bobby showed up for a surprise visit.

Fortunately, K-Cav's a sucker for the grand romantic gesture and, before long, she and JB are sharing a hotel room locking lips and making sure word of their little Sin City adventure slowly trickles back to L.A. (and Audrina Patridge). But will their vacation fling lead to something more? Watch as K-Cav and Justin's fun night out quickly devolves into a high stakes morning after. Hey, that's what you get for waking up in Vegas...

It's been some time since Joe Zee ordered Erin Kaplan to show Olivia Palermo the ropes, and natch, we've been waiting anxiously to see Elle's PR Director finally take Liv under her wing. But from the looks of this video, that's all far from happening on next week's City. Plus, over at People's Rev, Kelly Cutrone's putting the kibosh on Roxy Olin's creative brainstorms. Holy office anxiety! Watch as Roxy's efforts to help Whitney/impress Kelly fall just a little bit short while Erin and Liv get into yet another turf war.

Wednesday night, roomies (slash costars, slash coworkers slash joined-at-the-hipsters) Whitney Port and Roxy Olin got all dolled up and hit the party circuit in their red carpet finest. So how'd they avoid stepping on each other's toes? Simple: they stayed approximately three thousand miles apart. Yep, while Whit went West Coast wildin' at Us' Hot Hollywood party (along with Hillzies Stephanie Pratt, Kristin Cavallari and Audrina Patridge), Roxy held down the fort in NYC at the taping of the 2009 mtvU Woodie Awards.

Check out both gals' gorge going-out ensembles (BTW, is it bad that Whit's lacy white frock reminds us of the "doily" dress from Reality Bites?!) and tell us whether you're more in love with Roxy's loose locks/copper-colored wrap -- or Whitney's delicate ringlets/beaded baby-doll.

As the reigning smog capital of the world, L.A's pretty much the last place you'd wanna go to bone up on your astronomy. 'Course, if it's stargazing you're after, you won't find a better view on this side of the equator -- and last night, all the biggest/brightest stars of Tinseltown were out at Us Weekly's annual Hot Hollywood party.

So who lit up the room? Amid the usual melange of musicians, socialites and actresses (like Leona Lewis, Nicky Hilton and Eliza Dushku), Hillzies Kristin Cavallari, Audrina Patridge and Stephanie Pratt glimmered and shined in glitzy metallics, sparkly bangles and sexy corsets. Take a look at our Hills gals' shimmery red carpet style and let us know who you think had the most dazzling dress of the night!

Ever worn a body-hugging corset dress so tight it practically cut off your circulation? Or treated yourself to a gorgeous up-do that took 45 minutes (and 200 bobby pins) to remove? Yep, we've all done things we're not exactly proud of in the name of fashion, like squeezing our feet into strappy stilettos two sizes too small (what, they were Manolos!?) or wearing a flimsy faux-fur vest in the dead of winter (hey, at least we LOOKED warm). So who's the newest member of the Stylistas Anonymous club? City star Whitney Port! Check out her SOS tweet and find out why she was thisclose to taking off her tights!

Ever heard the saying 'fake it til you make it'? Well, given the current financial sitch, our closet's mostly packed with discount designer duds (i.e. Marc Jacobs markdowns) and items that could almost pass for the real deal. And since not everyone grew up on a steady diet of Loehmann's and Filene's Basement, we thought we'd share some of our tricks of the trade and show you how to get the look for less! Starting with: Lauren Conrad's latest red carpet ensemble.

LC looked like a million bucks at last night's Samsung launch party, sizzlin' in an LBD (with sexy, ruffled skirt), a flowy black cardigan and playful peep-toe pumps. Natch, we'd love to steal the clothes right off her back, but since we're stuck on separate coasts, we went to Forever21.com instead and found these similar styles (we particularly heart the tiered spaghetti strap dress!).

The best part? All together, the dress, cardi AND heels come out to just under $80 (the priciest item, the three-quarter length sweater, is only $27.80). Which means you'll still have plenty of loot left over to splurge on LC's metallic green mani-pedi before showing off that toe cleavage! Just make sure your nails are 100% dry before you go patting yourself on the back...

First, Gary gets chewed out for saying too much. Now, Janna and Tara are getting knocked for keeping their pretty little mouths shut. So what's a junior assistant to do? Well...

In this deleted scene from Styl'D, Tara makes herself at home at Julie Weiss' place, taking a swig of OJ and dishing out a side of revenge. Check it out, then try to imagine the look on Julie's face when she finds out what happened to her toothbrush...

Susie thought she was getting a lucky break by going up against Kim, but from what we saw of their battle royale, this one's not even close to over. So far, this Ruins has bloody knees, blistering fingers and enough rope burn to last two lifetimes. In fact, there's pretty much only one thing it doesn't have: a clear winner.

Sure, Susie's undefeated in the RW/RR ring, but Kim's fast, strong and, more importantly, not afraid to get her hands dirty. And since neither one of these girls has any intention of callin' it quits, we thought we'd throw it over to you and find out who you think has what it takes to win.

+ Think Susie's winning streak's about to come to an end? Or is Kim one tug away from defeat? Take the poll and tell us who's gonna come out on top!

First, Tonya and Veronica get into a catfight over who's crazier (pssst, it's a tie!), then Brad and Darrell try and figure out who's got the bigger ego and now Susie's huffing, puffing and damn near blowing a gasket over some lousy popcorn and M&Ms. So what gives? Well, according to her, these challenges have a way of making everyone loco, and something about seein' KellyAnne and Casey eavesdropping -- with "snacks," no less! -- made her wanna tear their eyes out. Hear Susie explain why she got all bent outta shape (spoiler: it involves giggling and underwear!), plus check back later to find out Casey's jokey take on Susie's rampage.

+ UPDATE: Casey fires back! Here's what the Ruins alum had to say about her role in the candy-coated catfight!
