Yesterday Kristin Cavallari went shopping at Arcade on Melrose, and the Hills honey looked oh so fabulous in this casual yet chic outfit. Maybe it's her bubbly personality or those luscious locks (look out Jennifer Aniston!), but we can't think of anyone else who makes a plaid button down look this sexy.

Katy Perry has really put Russell in a great mood! Props to her.

We spotted the happy-go-lucky Brit grabbing lunch at Le Petit Four in West Hollywood without his ladylove on Monday, but that's okay - just look at that grin on his face! This relationship better last a while, because we think the couple is a perfect match.

Yeah, not so hot! Blake Lively actually dresses like every other New Yorker when the cameras aren't rolling. Shocker!

Thankfully, she's still stunning.

The office was divided on the subject of Brad's grayish chin curtain, some of us think it's hot in a dirty sexy sort of way, while the others just think it makes the former sexiest man alive look old, tired and stank. It also makes it kinda hard to fantasize about him without conjuring up images of beard burn, which, if you've never had it, is NOT fun!

So we ask you, our loyal viewers to be the tie-breaker:

Argyle = So hot right now!

Tom Cruise's wife went shopping at Maxfield with her mom the other afternoon in a sexy sweater. Hmm, is this her new signature look? I miss the boyfriend jeans!

Sienna never struck me as a real girl's girl, which is probably why she's usually only seen in the company of other guys, whether they're her boyfriend or another woman's husband or both!

But it looks like she's found a way to combat feeling lonely in New York, by having her trusty dog with her at all times!

And the little bitch is certainly cute. Sienna's dog's not too bad either!

Four thousand Scientologists attended a huge party in England last weekend to celebrate the 25th Anniversary of the International Association of Scientologists, reports Us...

Tom Cruise, Katie Holmes and daughter Suri made a surprise appearance at the event in which Cruise himself addressed the crowd with, "We are in this together!"

An attendee says that "Tom looked like he was in heaven" while Katie was "doing her best to look as enthusiastic."

John Travolta and Kelly Preston were also there, but appeared more "muted."

Most interestingly, Cruise was overheard chatting with a guest about the protesters outside, calling them "squirrels." He also said that they were "stuck in an electronic incident. It makes me so angry!"

Whoa! How rude. Wait, what does that even mean?

Aww, I guess no more shooting SatC 2 for a while! Sarah Jessica Parker was spotted leaving her NYC pad with son James and heading to the airport...

But where are the twins? We haven't seen them since their birth!
