The “Kill Bill” singer joined Kendrick Lamar on stage in the middle of the Kansas City Chiefs vs. Philadelphia Eagles game.

It isn't just Kendrick Lamar who has been making all sorts of waves after his iconic performance at Super Bowl LIX on Feb. 9. One of his guest performers in the highly anticipated halftime show was r&b star SZA, who sang two of her songs with the renowned rapper during her Super Bowl cameo.

While it doesn't happen every time, the Super Bowl halftime show headliner usually brings out a handful of surprise guests to perform alongside them on the night. Last year, Usher brought out Alicia Keys, Lil Jon, Ludacris, Jermaine Dupri, H.E.R. and Will.i.am!
