Zach Galifianakis once told Ke$ha how bad he thought she was to her face

Zach Galifianakis is not a fan of Ke$ha, and he’s not afraid to tell it to her face.

Ke$ha has said in the past that she had a crush on ”the fat guy from The Hangover," otherwise known as Galifianakis, but the feelings are one-sided.

The Hangover star told Rolling Stone he once told the glitter-loving singer how bad he thought her music was to her face.

“I saw that Ke$ha woman the other day,” he said. "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, 6-year-olds – and it’s a bad message.’"

During a recent interview promoting The Hangover Part II, he was told she’d also like to do a porno with him in the future.

His response?

“Good for her. She’s a great influence,” he said sarcastically.
