Wife Kim Kardashian supported her hubby from the crowd -- with a ton of selfies, of course.

Taylor Swift isn't the only one who can bring A-list guests on stage!

Kanye West headlined FYF Fest in Los Angeles Saturday night -- a fill-in after Frank Ocean dropped out just days before due to a reported scheduling conflict -- and he turned his last-minute addition into one worthy of the hype.

The rapper started his set solo, performing "No Church in the Wild," which apparently confused people as Ocean's vocals could still be heard on the track, according to Entertainment Weekly.

Plenty of hits were performed throughout the night, as West himself said at the end of his set, "I've got like 10 minutes and I've got like 10 years of hits for y'all." (Drake, by the way, made very similar comments when he headlined the first weekend of Coachella this year. Gets the crowd hyped up either way, that's for sure.)

Those hits included "FourFiveSecond" and "All of the Lights," which both featured the 38-year-old superstar's biggest surprise of the night -- Rihanna!

First, the 27-year-old singer was handed the mic from the stage to sing the chorus of "FourFiveSeconds," and even she seem a bit surprised, albeit happy to oblige.

Then she was brought onstage for her and Kanye's collab "All of the Lights." In typical RiRI fashion, she vamped her way through the song, much to the delight of her and Kanye's fans.

In addition to Rihanna, Kanye also surprised fans by bringing up Travis Scott to sing his heart out on the mega songs "Upper Echelon" and "Antidote."

Though she didn't make an appearance on stage, West's wife Kim Kardashian was at The LA Sports Arena & Exposition Park to support him. She clearly enjoyed her whole night, bringing along sisters Kendall Jenner, Kourtney Kardashian and Khloe Kardashian to rock out at FYF.

The 34-year-old reality star even shared a selfie with her hubby (naturally), captioning the sweet photo of the two with a quote directly from Kanye's song, "Bound 2."

Looks like Kanye really did find his one good girl.

The 12th year of FYF Fest continues Sunday in Los Angeles, with Morrissey heading, as well as sets from D'Angelo, Bell & Sebastian, FKA Twigs and Solange.
