Mariah Carey hit the waves during her Puerto Rican vacation while riding a longboard along with three canine companions. So cute!

Wearing a low-cut and sexy black wetsuit, a smiling Mimi looked confident out there on the surf. We're surprised her wetsuit isn't "pink yet lavender" - her signature color.

Next time, Mariah, maybe you should take only one of the dogs for a ride. Going surfing this way seems a bit ruff ruff!

Show me your teeth pants!

Ashlee Simpson does look hot here, but I think we can all agree that the so-called leggings she's wearing look more like tights! I'm all for showing some leg, but you should make sure the garment you're covering them with is a little more opaque...

After hearing the news that her father Michael Lohan is engaged to Jon Gosselin's ex-fling Kate Major, Lindsay Lohan had a few things to say!

X17online first broke the story that Michael asked Kate to marry him after traveling to Florida and asking her father's permission, and while the newly engaged couple is thrilled, Lindsay definitely isn't being a supportive daughter!

Linds told Us Weekly, "I'm gonna vomit! I so didn't need that info ... Yuck!" She hasn't tweeted anything yet, but given her harsh reaction to her dad's relationship status, this doesn't look to be the end of it.

Hmm, I guess she won't be at the wedding! If it gets that far...

Katie Holmes was snapped returning to her NYC digs yesterday evening in a questionable pair of pants, and considering she spent the bulk of the day on set, she appeared to be in good spirits.

So what was Suri up to? On Tuesday afternoon we spotted her riding in her nanny's arms, and she definitely wasn't in the mood to have her photo taken. Bad hair day or did she miss mom?

Yesterday we spotted Jennifer Garner and her darling daughters Violet and Seraphina grabbing frozen yogurt in Santa Monica, and when Jen was busy carrying V, we got a peek at little Seraphina standing on her own two feet! Now that she's close to walking, I guess Jen can keep on carrying 4-year-old Violet...

Yesterday Britney Spears and her agent/lover Jason Trawick stopped by Barneys in Beverly Hills, and when they were done shopping, they appeared to be having a nasty argument in the car!

An X17 photographer on the scene tells X17online exclusively:

"It was so strange. Britney was driving and they just started fighting and it was getting really heated. At a stop light they didn't even care that photographers were watching what was going on - Britney was crying and Jason was upset, and she seemed very aggressive towards him. It was definitely something serious."

Wonder what this was about? Did Jason finally drop the bomb on Britney that he's not a fan of her music? Did he dump her again? Or does this have to do with the conservatorship? Oh, to be a fly on the wall inside the infamous white G Wagen...

Backlash? What backlash? Looks like Mischa Barton is still taking a big bite out of life!

The former O.C. starlet, once so lovely-looking and glamorous, continues on her downward spiral. Aside from guest-starring as a hooker on Law & Order and putting her mansion on the market, Mischa hasn't been doing much except wear unflattering clothes in public. Here we go again!

The newly blonde starlet hit up the gym this afternoon - perhaps in response to critics complaining about her weight gain? - only to chow down on some grub soon after.

Not the best idea, girl! But it proves that you don't care what people think, so kudos for that!

Check out Mischa acting fidgety and strange outside of Starbucks. Why so antsy, M?

And people are taking notice!

Jennifer Aniston's latest comedy, Just Go with It, has her playing a "pretend wife" to Adam Sandler. Le sigh. And unfortunately, the crew has been dressing her in dowdy outfits... until now! The perfect-bodied actress was spotted on set in Santa Monica just now in a slim and sexy dress.

They must be shooting scenes for the second half of the movie when Aniston's character gets all gorge!
