We can only assume that Rihanna was simply getting a checkup, but after suffering a beating like she did, you've got to wonder if there was another reason she visited the doctor's office yesterday afternoon.

We snapped the R&B superstar at a medical building in Beverly Hills, where she stayed for about an hour. Of course, the starlet rocked some serious hair, a pair of sexy pumps and her trademark oversize sunglasses for the adventure. Hey, this is Rihanna we're talking about - girlfriend wouldn't go to the mailbox without spending at least a few minutes dolling herself up!

Once upon a time Lindsay was a Plastic, and Ali is her baby sister, so we can call her Baby Plastic, right?

The 15-year-old aspiring celeb was snapped in Hawaii yesterday, and instead of rocking a one piece like Linds, Ali showed off her curves in a striped bikini. Yeah, we can't believe our eyes either...Ali looks like a 25-year-old FHM model, not a high school sophomore...

After she went shopping for hats, Paris hit up The House of Luck and Love in Beverly Hills to pick out some bling. More specifically, a tiara and some heavy duty diamond necklaces! We know she loves Doug, but diamonds are really a girl's best friend!

Oh, and they brought along a super-hot guy with 'em!

At first glance I was all, "Whoa, Justin looks so much buffer than usual!" But I'm sure this dude is just some fitness trainer. Justin better hope Jess doesn't get the hots for him! Time to (finally) put a ring on it, maybe?

Jealous?

The Basterette - also known as Jennifer Aniston - was again spotted on set decked out in some comfy clothes. Is it possible for Jen to keep looking cute forever? I think so!

Nicole Richie's babydaddy was spotted at Coffee Bean in a bright zip-up jacket...

Oh yeah, and his hair's still blonde. Hot or not?

How adorable is Violet? Uh, she's SO adorable. Bennifer's eldest daughter is in the Big Apple, out shopping with her mom. How come we never see her out with dad?

Nah, that's Angelina Jolie - this is just Jennifer Love Hewitt!

I actually don't mind her wearing this big, billowy black dress... after all, the top half of J.Love has always been pretty spectacular! But with the wind blowing all around her, that dress is not doing anything for her super-slim figure!
