Zach Galifianakis engaged to Quinn Lundberg

What does this mean for the Wolfpack? "The Hangover" star Zach Galifianakis has proposed to his longtime love Mary Quinn Lundberg -- and, according to sources, they've already sent out wedding invitations.

Celebuzz reports that Galifianakis will wed Lundberg on August 11, and that he included a fun twist on the traditional invite. "Zach included a drawing of himself and his bride-to-be. He made sure he looked like a little troll, while Quinn is a stunning tall blonde princess," their source says.

Lundberg, a trained dancer, is VP and cofounder of Growing Voices, a charity that seeks to incite change "at the grassroots level." Currently, they're working with Cambodian "low priority villages" to clear mines and UXOs.
