Sure she supposedly tried to commit suicide a few weeks ago, but now Mischa Barton is all smiles and is apparently doing quite well. Mischa told OK!, “I’m feeling great! I’m really happy”

She seemed to be doing well at the Arizona Ice Tea-sponsored party for Music Unites. Mischa showed up in a very interesting outfit, no doubt trying to distract from her recent health history. Mischa spent most of the night drinking water, chatting with male partygoers, mainly Richie Rich, and left around 10:40 pm to go watch True Blood.

Others are also seeing a better side of Mischa. One guest said to OK!, “She seemed to be in a good mood. She was smiling and appeared to be genuinely happy.”

Mischa is back to work on her CW show The Beautiful Life. Reps deny that there was any attempt at suicide, but you know, when you’re playing a pill-popping supermodel, it’s going to leave some mark on your usual day. Good luck Mischa!
