Katy Perry goes all out as Jane Lane from Daria at Maroon 5‘s Halloween Party held at the Hollywood Forever Cemetery on Wednesday (October 31).
Emma dressed as a cat, and posed for a picture next to someone in a Scream mask (Emma starred in Scream 4). Rose looked pretty as a Snow Queen. Chris rocked a Hawaiian shirt, while Aziz chose a Thomas the Tank Engine get up. Adrian looked tough as a ninja!
