Which Hollywood Actress Is Wearing a Sock Monkey Halloween Costume?

Comedic star is married to an equally funny and oftentimes controversial actor

There's some monkey business going on in Hollywood.

Monday night one movie-star mom went all out with a sock-monkey-doll Halloween costume.

Wearing the head-to-toe ensemble, this funnylady (with an equally funny and often controversial other half) was unrecognizable. Think you definitely maybe know who it is?

If you guessed Isla Fisher, you're correct!

The 36-year-old Wedding Crashers star attended a Halloween party in Beverly Hills with hubby Sacha Baron Cohen. The DIctator himself also got into the holiday spirit, pairing a gorilla mask with a cow bodysuit.

Their daughters Olive, 5, and Elula, 2, sure are lucky to have such fun, festive parents.
