Britney Spears took the stage at Madison Square Garden in New York City Sunday night to perform at the MTV Video Music Awards.

Spears, 34, took the stage after Beyoncé’s mind-blowing performance. Kim Kardashian West introduced the starlet, who came out singing her new single, “Make Me.” Spears was joined on stage by G-Eazy, and even sang a few lines of his song “Me, Myself & I” — or did she? Fans of the singer took to Twitter to complain about her lip-syncing.
