Halloween: Heidi Klum monkeys around in her 2011 costume

Heidi Klum isn't just famous because she's a supermodel and the host of the ultra-successful "Project Runway." She's also built a reputation for kick-butt Halloween costumes.

Klum's 2011 costume, though, may just be her strangest yet. The 38-year-old mom decided to go the playful route this year, donning a furry bodysuit, skullcap, ears and teeth that definitely put her in the top percentile of hot primates. She shared a sneak peek with Us Weekly.

In the past, Klum has dressed as a many-armed blue Indian goddess, an alien robot, a cat and a snake-wrapped apple a la Garden of Eden.

Here at Zap2it, we think Klum's 2011 get-up also bears a striking resemblance to Weekly World News mainstay Bat Boy.
