Whoops! She's got the G and L down, but not the T. Katy Perry was off exercising in Bev Hills again - she's such a gym rat! - and forgot to wear her Jersey Shore inspired workout shirt. That's okay, girl looks good without makeup so we can forgive her!

Oh, and is Katy pro the legalization of marijuana? Watch the vid below to see her answer!

Cutest. Picture. Ever. Honor got in some "me" time while riding around in a wagon - being pulled by the nanny - in Bev Hills on Monday and, yes, she is starting to become our fave celeb kid. Sorry Harlow!

And where did part of the cast film one of the first scenes from the second season? In a laundromat! Yeah, you can't even make this stuff up. GTL 4-eva!

Sidebar, Pauly D's bod is starting to get a Situation of its own... think he's the hottest "guido" on Jersey Shore at this point? Maybe, just maybe. The Sitch has some competition!

Jim Carrey and Jenny McCarthy have split, the actor confirms on his Twitter.

Minutes ago, Jim tweeted:

"Jenny and I have just ended our 5yr relationship. I'm grateful 4 the many blessings we've shared and I wish her the very best! S'okay! ?;^>"

Jenny posted a message of her own:

"Im so grateful for the years Jim and I had together. I will stay committed to Jane [Jim's daughter] and will always keep Jim as a leading man in my heart."

The couple were together for five years, with Jim acting as a father to Jenny's son, Evan, who suffered from Autism.

Jim welcomed his first grandchild in late February, and Jenny seemed just as excited as her beau to welcome the little boy into their family, tweeting, "Yes I'm a grandma!"

Last night photogs caught a glimpse of a dinner party at the Chateau Marmont, where Cameron Diaz was sitting next to none other than Ryan The Office temp!

Clearly, Cam didn't want to be caught on camera, but is that because she didn't want to be seen with the less-than-sexy Novak? Or was she just having a bad hair day?

The California Attorney General Jerry Brown revealed that Corey Haim had obtained 553 doses of prescription drugs in the month before he died.

"In a period of 32 days, Corey Haim obtained at least 553 doses of potentially dangerous prescription drugs," Brown said. "He died five days later. It's important for people to understand that legal, prescribed drugs can be just as dangerous as street drugs, and doctor shopping can be deadly."

The former child star had collected more than 195 tablets of Valium, 194 tablets of Soma, 149 tablets of Vicodin and 15 tablets of Xanax, in prescriptions obtained through aliases, emergency rooms and urgent care facilities and filled in multiple pharmacies.

Corey Haim passed away on March 10th, after a bout with pneumonia, which was exacerbated by his drug addiction.

Another glimpse of an Olsen! On Sunday the super-rich fashionista attended her boyfriend's opening night play on Broadway with her sis, and yesterday Ash shopped around the meatpacking district in NYC.

Think she'll be getting hitched to Justin Bartha anytime soon? They seriously make such an adorable couple!
