Queen B shocked fans at Coachella when she jumped on stage during her sister Solange’s performance on Saturday.

The sisters did an impromptu dance number to Solange’s single, “Losing You.” Beyoncé was not scheduled to make a cameo notes the New York Daily News.

“Give it up for my dancing partner and my favorite person in the world, my sister Beyoncé,” said Solange at the end of their performance.

Before Beyoncé walked off stage, the sisters shared a sweet hug.

Beyoncé’s hubby Jay-Z also made a surprise appearance. Three hours after Beyoncé hit the stage, Jay-z jumped on stage during Nas’ set notes the Huffington Post. The former feuding rappers performed Jay’s classic hit “Dead President II.” Many rap heads attribute the song for starting the beef between Jay and Nas.

Jay then performed “Where I’m from” and Nas closed out his set with another guest appearance from Diddy. Diddy and Nas performed their hit “Hate Me Now.”

Other celebs spotted Saturday at Coachella include Katy Perry, Robert Pattinson, Selena Gomez, Vanessa Hudgens, Kylie and Kendall Jenner and Jared Leto.
