Canada’s Avril Lavigne performed “Girlfriend” at Halsey’s annual Halloween party in L.A. on Friday night – and got a little help from Halsey.
Lavigne, dressed as Madonna, and Halsey, as Marilyn Manson, belted out the 2007 hit and lucky for us, some partygoers captured it on video.
"Girlfriend" was one of the singles off Lavigne's third studio album, The Best Damn Thing, and went to No. 1 in Canada.
Lavigne kicks off the European leg of her Head Above Water World Tour in March.
Watch part of the energetic performance below:
