Three weeks after Kanye West blasted the Grammys and album of the year winner Beck, the rapper has taken to social media to apologize.

On Thursday, West tweeted, “I would like to publicly apologize to Beck, I’m sorry Beck.”

Shortly after, he also made an appeal to Bruno Mars, who he “used to hate on,” and said he would even like Mars to sing the hook on a song he produced with 88 Keys and Puff Daddy.

I also want to publicly apologize to Bruno Mars, I used to hate on him but I really respect what he does as an artist. — KANYE WEST (@kanyewest) February 26, 2015

I also would love for Bruno to sing this hook on this song 88 Keys / Puff and I produced… I even asked Tyler to shoot the vid. — KANYE WEST (@kanyewest) February 26, 2015

During the Grammys, West nearly stole the moment when Beck won the award for album of the year, as it looked like he was about to jump on stage to protest the win. He sat back down, only to slam the Grammys the next day for their decision, saying they should “respect artistry” and that Beyonce should have won.

Beck didn’t seem to mind, though. “I was just so excited he was coming up,” Beck said after the show. “He deserves to be onstage as much as anybody. How many great records has he put out in the last five years, right?”

West’s apology came the same day he broke down in tears during a BBC Radio 1 interview. While talking about a mentor of his, late fashion professor Louise Wilson, West started to cry, and had to pause the interview before continuing onto another subject.
