Kanye tweets apologies to Beck and Bruno Mars

(CNN) — Kanye West is on an apology spree.

In a series of tweets, West reached out to singers Beck and Bruno Mars to express his contrition over his well-documented disses.

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

Beyonce backer

West stole Beck’s spotlight this month when he won a Grammy for album of the year. In an interview later, he asked Beck “to respect artistry” and give the award to Beyonce.

Though West did not grab Beck’s microphone like he’s done in the past, his brief stunt was similar to a 2009 incident when he stormed the stage during the VMAs and declared Beyonce should have won an award instead of Taylor Swift.

Bruno props

Bruno Mars got more than an apology Thursday.

“I used to hate on him but I really respect what he does as an artist,” West tweeted.

West then asked him to sing a hook on the song 88-Keys, which he co-produced.

There was no immediate response from Mars or Beck.
