Charlie Sheen and partying hard go hand in hand!

The former Two and a Half Men star kicked up his heels and raised his arms at the wrap party for Anger Management at Mixology 101 in LA.

Looks like Denise Richards' ex has also moved on to a new young girl. Sheen, 46, Tweeted that he had an "epic" time at the party. We believe it!

But on their way out, his lady friend didn't seem too happy. What gives?
