Zach Galifianakis Lectures Ke$ha

Memo to Famous Ladies: when Zach Galifianakis approaches you, make a run for it. The man has no tact, and he might hurt your feelings.

The "Hangover" star is a comic idol to his legions of fans, but he's shamelessly striking out with female celebrities left and right by A) insulting them at parties and then B) smearing them in the press afterward. Here's what Galifianakis had to say about Ke$ha in an interview with Rolling Stone:

"I saw that Ke$ha woman the other day. She was sitting by herself, and I walked up to her and said, 'Listen, I got your e-mail. Your music is really bad! I don't know who listens to it, but I imagine it's, like, six-year-olds -- and it's a bad message."

The glitter-shooting pop star previously reached out to the actor to ask him for a drink -- instead of politely declining the offer, he insulted her music. Another woman Galifianakis loathes: January Jones. In an awkward encounter with the "X-Men" star, he sniped that "everybody's going to forget about you in a few years" -- and then blabbed about the exchange in an interview.

Playing Devil's advocate: nobody could ever call Galifianakis fake. Or not funny. But they would call him smug and socially awkward. And kind of a jerk.
