Halsey and Avril Lavigne teamed up this weekend for a rockin’ collaboration at Halsey’s annual Halloween party in Los Angeles. Halsey invited Avril on stage to join her for a performance of Avril’s classic “Girlfriend.”
Of course both Halsey and Avril got into the Halloween spirit with their costumes. The party’s theme had folks dressing up as rock stars of the 60’s, 70’s, 80’s & 90’s, with Halsey dressed as Marilyn Manson and Avril dressed as Madonna.
