Hollywood is speculating about why Eva Mendes checked herself into Cirque Lodge in Utah for substance abuse problems. Insiders say "Eva has always been cool, never overindulged in public" and the one thing she struggled with was her weight. Kirsten Dunst checked into the same rehab looking thin as a toothpick. Just about every female celebrity arrested from Paris to Nicole, Lindsay, along with Britney Spears, has had prescription Adderall (which is prescribed for ADHD) in her purse. In Hollywood this drug is not used for ADHD, it's a form of Dexedrene and it keeps one awake while killing the appetite. (College students love it.) Pills are indiscriminately popped like aspirin day and night. Recently we've learned that they are very addictive and can cause all kinds of craziness. Just maybe, this explains why so many Hollywood women are having behavior problems

Kirsten Dunst didn't get a whole lot of sympathy last month when her penthouse suite at the SoHo Grand Hotel was burglarized. Crooks stole her wallets, cash, cameras, and iPod along with handbags - and one handbag was worth $13,000! (It's difficult to feel very sorry for a person with a $13,000 handbag.) However, it did throw a big scare into Kirsten and she has since hired a bodyguard. He keeps an eye on her home and accompanies her when she goes out alone at night.

Kirsten Dunst seems to be a bigger star in England than she is in the US- maybe thanks to the one-two punch of Marie Antoinette and Spiderman. She and her rocker boyfriend Razorlight's Johnny Borrell went to the Electrowerkz nightclub in London and they wanted a PRIVATE VIP room but the club didn't have one. The club accomodated them by quickly creating a VIP room out of a dressing room.The royally treated couple occupied the private room until 4 AM and reportedly consumed so much beer, they had to be helped out the door. No, they didn't drive.

Guess who? SOMEBODY hates running into photographers when she's looking a little drab. Kirsten Dunst left her rocker boyfriend Johnny Borrell of Razorlight back in London and she's getting things done in Beverly Hills. Maybe she's in a hurry to get back to him. Marie Antoinette made her a huge star in the UK and they are very impressed with her there.

Orlando Bloom has moved on from superskinny Kate Bosworth to ultra buff Jessica Biel. Kate looks like she can barely carry her handbag while we figure Jessica could bench press Orlando. The playful pair turned up at Hyde Saturday - Orlando wore his usual goofy hat and Jessica was dressed in a short black and white dress and boots. They were on a double date with Orlando's Elizabethtown costar Kirsten Dunst and a friend of Orlando's called Charlie. They danced and partied and Orlando couldn't keep his hands off Jessica. Another clubgoer said "When he wasn't smooching her or nuzzling her neck, he was patting her round bottom." Must have felt good for a change.

The Marie Antoinette premier party at Chateau Marmont was a huge success and the celebrity crowd ignored their diets and feasted on mountains of sweets - inspired by the movie. Revved up partiers couldn't help gossiping about the movie's star Kirsten Dunst and her mysterious love life. Since splitting with Jake Gyllenhaal, Kirstin is VERY low key about her personal life. The buzz of the party was that Kirsten and her Elizabethtown costar Orlando Bloom have resumed their romance. Fueling the party rumors was the fact that Orlando was there - but seen lurking behind trees and bushes most of the evening! The fact that he avoided Kirsten - and almost everyone else - but stayed at the event for a long time- seemed suspicious. But lately he's been seen openly hanging out with Penelope Cruz. Is she a decoy or the real thing?

Fashionistas might assume these are five Vivienne Westwood models backstage waiting to hit the runway. A close inspection reveals it's actually our own little Kirsten Dunst dolled up as the 19 year old queen of France, Marie Antoinette, surrounded by her ladies in waiting. That's what they called girlfriends in those days.
