Katie Holmes: Cupcakes for Bailee's Birthday!

Katie Holmes leaves her trailer clutching a script on the set of her new movie, Jack and Jill, on Monday (October 18) in Beverly Hills, Calif.

The 31-year-old actress is working alongside Adam Sandler, who cross-dresses in the film and stars as both Jack and his wacky twin, Jill.

Katie recently stopped by the Wizards of Waverly Place set to help her Don’t Be Afraid of the Dark co-star, Bailee Madison, celebrate her 11th birthday.

She surprised Bailee, who was filming an episode of the hit Disney Channel series, with cupcakes and a birthday card!

FYI: Katie is wearing The Shirt by Joe’s.
