We just can't quite figure out what she is!
Leona Lewis was just one of the many faces to grace Barcadi/ Maroon 5's annual Halloween bash last night and LL got very festive with her costume indeed!
Gurlfriend has a Carrie meets Teen Wolf meets zombie thing going on here. It's definitely very spooky, scary! We'd hate to have crossed paths with her! Woooo!
Hope your all Hallows Eve was a blast, LL!!
