Serena Williams joined the singer on stage for a performance of "Sorry", a song in which the tennis star appeared in the music video.

Beyonce then announced that "someone special" would be joining her onstage and her husband Jay-Z came out for a duet of "Drunk in Love."

For her encore, Kendrick Lamar teamed up with Beyoncé on the pop diva's track "Freedom," a performance that ended with the two splashing furiously in the pool situated at the front of the stage.

Beyoncé also staged the live debut of Lemonade's "6 Inch," with the singer suspended upside down for the first ever performance of the track.
