Kanye West just pulled a Taylor Swift.

During his performance at FYF Fest on Saturday in Los Angeles, the rapper (who filled in for Frank Ocean) surprised the audience when he brought Rihanna onstage with him. The resident bad gal also seemed surprised, as she was just taking in the show from the crowd.

But like the pro she is, RiRi took the mic when West handed it to her during his performance of “FourFiveSeconds,” which she’s featured on. She then turned to the crowd and said, “LA, make some noise for my n***a Kanye!”

The rapper, who’s married to reality queen Kim Kardashian, also got the Barbadian performer up onstage to sing her part of “All of the Lights.” Naturally, the audience went nuts.

West was a last-minute addition to the roster, stepping in for Ocean, who dropped out last week, Gossip Cop reported.

“We’re really sorry that due to a scheduling conflict beyond our control, Frank Ocean is not going to be able to appear at FYF Festival as planned,” Ocean’s reps said in a statement obtained by Entertainment Weekly.

They added that he “had really been looking forward to the performance and to seeing all of his fans.” But West paid homage to his fellow hip-hop artist by opening his set with the track “No Church in the Wild,” which features Ocean’s vocals.

Kanye West to the rescue — all day, all day.
