Off The Wagon???

Kirsten Dunst checked herself into rehab just a few months ago, but (like Lohan) the actress has already resumed her hard-pAArtying ways.

The NY Daily News is reporting that Drunkst’s sobriety may be slipping.

Recently rehabbed Kirsten Dunst partied hard last week for her 26th birthday at Bowery Electric, the new rock bar that has taken over the space of creepy voyeur haven Remote Lounge.

We can’t say for sure what the newly sober Dunst was consuming, but spies say the actress looked a lot worse for the wear as she tumbled out on to the street hours after midnight, with girlfriends gripping her arm.

How long until she goes back to rehab???
