David Arquette has been out and about in Hollywood and looks better than ever! Thursday night David hit up the Samsung Infuse 4G Launch event at Milk Studios.

“He looked really happy,” a partygoer at Arquette’s table tells Celebuzz. “It seems like his recovery is going well, he drank water the entire time.”

David entered rehab in early January. 

Our source, who says he was hanging out with a mystery brunette for most of the evening, said that despite still being separated from wife Courteney Cox the actor was in a great mood.

“He was so friendly with everyone, taking pictures with fans and talking to any guests who came up to him,” adds our insider.

Glad to hear he is doing so well! Arquette mingled with celeb attendees like Mark Salling and watched Nicki Minaj give a killer performance while Jennifer Hudson looked on from the side of the stage.
