On the one hand you've got Mariah - who always dresses so elegant and classy, wearing sunglasses at night. But that dress... I dunno if it shows off her best assets!

And then there's Tara. The once-promising young Hollywood actress turned party-too-hardy socialite. A better question might be, do either of them really belong at the prestigious Cannes Film Festival???

Adam Levine and his tatted up guns made another appearance at the Chateau Marmont today, but new lady love Cameron Diaz was nowhere in sight! Maybe they've picked a new rendezvous spot? I'm sure we'll catch them again soon - stay tuned!

Here's the thing: Ryan Phillippe is always hot, hot, hot. In real life AND in pictures. As for Abbie Cornish, she's stunning IRL! But in pictures? Not so much...

Well, things change! Abbie looks gorgeous in the top pic - well done! Not lovin' her outfit but at least she looks pretty, right?

Paris Hilton and Doug Reinhardt caught some rays at the Hotel du Cap Eden Roc pool over the weekend, and Miss P showed off her sexy beach bod in a printed monokini. Is it just us, or does she look a bit protective of her hunky bf? Hey, we don't blame her - Doug's a catch!

You must check out the hilariousness that is Teri Hatcher doing a stage dive into a pool in Miami after shaking her ass (and her tambourine) on stage - in front of her daughter, no less - and warbling a few ill-advised rock songs.

Total LOLs.

Sometimes I forget that Sharon Stone is, like, a mother! Hey, she's famous for starring in Basic Instinct, the most sexually provocative movie EVER! And now check her out in Coldwater Park playing with sons Roan and Laird. Sharon's no Jen Garner, but that doesn't mean she's not a good mom!

These Hollywood relationships never last long!

We spotted Cameron Diaz's ex(?) Paul Sculfor shopping at Kiehl's over the weekend... meanwhile across town, Adam Levine was gettin' cozy with Cam at the Chateau Marmont! Trouble in paradise? Or are they over now? So many questions!

She may have tried to hide her gorge face underneath a hat and glasses, but there's no disguising the sour look on Jessica Alba's face!

At least she looks light and summery in that beautiful green maxi-dress!
