Watch Britney Spears & Tinashe Perform “Slumber Party” Together For The First Time At KIIS FM Jingle Ball

Last month, Britney Spears released a new version of “Slumber Party,” a track off of her recent album Glory, featuring spaced-out R&B singer Tinashe. And last night, the two of them performed that new version together for the first time, bringing some choreography and a whole lot of backup dancers to LA’s Staples Center for 102.7 KIIS FM’s 2016 Jingle Ball. As DirectLyrics points out, their lip-syncing wasn’t great, but hey — practice makes perfect! Watch below.
