Last year the 33 year-old caused controversy when he ruined Swift's acceptance speech by snatching the microphone off her and saying she did not deserve to win.
But in a new interview with Funkmaster Flex on New York radio station Hot 97, West admitted he went too far when he said the 20-year-old's Best Female Video prize belonged to Beyonce.
He said he has since spoken to the Mine singer about the incident.
West said: 'She just talked about how people would come up to her in the grocery store and bring it up, and she would defend [me]. It's an amazing, compelling situation.
'I try to downplay it, but... I made a mistake, my timing was definitely, extremely off... If I hadn't said anything, everything would have just went smoothly.'
