Wilmer Valderrama jacket black baseball cap

Last night Wilmer Valderrama was spotted heading home after attending ex-girlfriend Demi Lovato's show at Club Nokia in downtown Los Angeles, and he tweeted, "Just left @ddlovato's LA concert.. No words to describe how proud I am of you.. Let your passion & self commitment inspire the world." Aww, how sweet! I mean, who knew the dude who played Fez on That 70s Show would be so moved by Disney-manufactured teenybopper rock?

Who else did we spot out and about last night? Josh Duhamel was seen grabbing some food at Tavern in Brentwood, and Josh Henderson hit up Tru nightclub in Hollywood. Check out the pics of the boys in the gallery below!
