Zach Galifianakis has reportedly popped the question to long-term girlfriend Quinn Lundberg.

The Hangover star, 42, is said to have quietly got engaged and has already sent out wedding invitations for their August 11 nuptials.

Celebuzz claims that the fuzzy funnyman has put his own unique spin on the upcoming event.

"The wedding invite is very Zach," an insider told the site. "While it has the formal and standard details of who, what, when, where including Zach's full name, Zachary Knight Galifianakis, and his fiance's, Mary Quinn Lundberg it is also very funny."

"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."

Zach's is one of Hollywood's top comedic actors, while Quinn, 29, is the co-founder of the charity Growing Voices.
