In an amazing change of heart, US rapper Kanye West has publicly apologised to Beck after he interrupted the rocker's acceptance speech at the Grammys.

West caused a stir when he stormed the stage at this year's Grammy Awards as Beck went to collect his Best Album award for Morning Phase.

His antics drew criticism from many musicians, including Smashing Pumpkins frontman Billy Corgan, who said this week he would have "knocked out" West.

"I've stood at that podium too and I'll tell you what, if somebody got up on my stage, I would knock them out. I don't care who it is, I would have knocked him out," Corgan said while appearing on the Seven Network's The Morning Show.

West had refused to apologise to Beck but it appears the rapper has had a change of heart.

"I would like to publicly apologize to Beck, Im sorry Beck," West tweeted.

West also used Twitter to apologise to another fellow artist.

"I also want to publicly apologise to Bruno Mars, I used to hate on him but I really respect what he does as an artist," he wrote.

"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," he added.

The public has definitely seen a different side of West this week.

West broke down in tears during a BBC radio interview with Zane Lowe. The rapper was remembering his fashion mentor Louise Wilson, who died last year, when he lost his composure.

West admitted his emotions had surprised him.

"That's never happened to me in an interview before," West told Lowe.

And Beck and Mars aren't the only musicians West has attempted to make amends with. The 37-year-old was spotted enjoying a meal with Taylor Swift at The Spotted Pig in New York City last week.

West famously humiliated Swift in 2009 when he stormed the stage the MTV Video Music Awards during her Best Female Video acceptance speech and told the crowd Beyonce deserved to take home the prestigious prize instead.

Asked for her opinion on the former rivals-turned-rumoured collaborators, Madonna said West was a "beautiful mess" who is always "saying inappropriate stuff".

She described him as "a brilliant madman" but added "I don't always agree with him".

"He can't help himself. He doesn't have the same filters other people have."
