KiKi In ReHab

Well, we know Kirsten Dunst checked into rehab this week. A day after Eva Mendes. Reps for both are not giving up what substance exactly these girl are hooked on, and Eva already checked out today. Kiki's problem I'll bet is pills. They are just too easy to get. Pills to get you up. Pills to get you down. The more you take. The more you need. You chase the high and then try and get down. Heath's death was a bit of a wake-up call. For alot of people, not just celebrities.

Then again, I look at this picture from over a year ago and I think, booze. Booze and weed. At least in this shot.

"She's not doing well," the source says. "People were pushing her to go in there but there was no intervention… She has been partying hard for a while and I'm sure the Heath Ledger thing put people over the edge."

Adds the source, "She’s been crying a lot lately, a lot built up. …Everybody hits that bottom where you feel [so] scared that that one heavy night of partying can really wake you up. It's good she's getting herself help."

Dunst, 25, who is a regular on the party scene in Los Angeles, was recently seen partying at the Sundance Film Festival where she hung out with Josh Hartnett at Hyde Lounge. Despite reports of erratic behavior at the festival, sources say Dunst was just displaying her usual "care free party girl antics."

"She was in a big group of friends and they were dancing their asses off by their table. They looked like they were having a great time and they were getting pretty crazy," said a source at the time.

However, the following day Dunst failed show up to her own Glamour magazine party. A source at the time said the actress "wasn’t feeling well."

Kirsten is being treated at the exclusive Cirque Lodge Treatment Center in Utah, the same facility where Lindsay Lohan spent nearly two months.

Still no word on what Eva and Kiki are into, but I'm trying to find out.
