Kanye West performed his long-awaited song, "All Day," during the 2015 Brit Awards. It features an appearance from rising MC Allan Kingdom on the hook and Theophilus London. The song was is produced by French Montana and Velous. Rumors were circulating that Kanye will perform a new song at the 2015 BRITs award show in London. The show, which is streaming live above, is the equivalent of the Grammys in the United Kingdom. According to UK outlet Mirror, 'Ye kept show organizers waiting until the last minute before confirming that he would perform a new song at the show. A source says that only seven people were present during his rehearsal and "He wants the first time everyone hears it to be special."

The Daily Mail is also reporting that Kanye was announced as the headlining artist early Wednesday morning after Rihanna bailed on the show last minute. Rihanna allegedly no-showed at rehearsals on Monday which sent the show organizers into a panic. After learning that 'Ye was in town (likely for another interview with BBC One's Zane Lowe, as shown below), they made him an offer and the rapper accepted. "BRIT bosses were understandably disappointed that Rihanna was a no-show, but - after some initial panic - they're delighted to have found a solution in Kanye," a source told the Daily Mail. "In fact, they know he's a huge star and won't simply just fill her shoes - but he'll own the stage and stun fans with one of the biggest performances of the year."

More reports are circulating that a Kanye West and Taylor Swift collaboration is a done deal.

The two met for dinner while in New York City after Swift approached Kanye and said she would like to work with him. No word on a release date.
