With the Formation World Tour wrapping up on Friday night, singer Beyoncé still had a few surprises in store for her fans at her final show at the MetLife Stadium in New Jersey.

It’s not easy to steal the limelight away from the multiple Grammy-winning performer, but that’s what Serena Williams did when she joined her on stage.

Reprising her famous role in “Sorry,” from Beyoncé’s Lemonade album, Serena took to her throne and twerked away, much to the crowd’s delight.

Afterward, Serena posted these snaps to her Instagram page with the fitting caption “Not sorry.”

Serena, who is no stranger to joining mega-popstars on stage, wasn’t the only celebrity at the star-studded event, with the likes of Taylor Schilling, Adrienne Moore, Hugh Jackman, and Frank Ocean all in attendance last night, as well as Beyoncé’s husband, Jay-Z who joined her onstage shortly after Serena’s performance.
