?Both Taylor Swift and Kanye West are set to perform on Sunday's MTV Video Music Awards, a source tells PEOPLE. But the stars are not expected to share the stage during the ceremony at L.A.'s Nokia Theater.
While West's performance was announced last month, Swift's appearance was set to be a surprise. Other previously announced performers include Drake and Usher.
The two made headlines when West infamously interrupted Swift's acceptance speech as she attempted to collect her best female video trophy at 2009's ceremony. (West thought the award should have gone to Beyoncé.)
Weeks before the ceremony, this year's host, Chelsea Handler, said she'd love to reunite the pair on the show. "We've never really seen them together since then," she said.
West has subsequently apologized to Swift, and even Tweeted that he had written her a song, "that's so beautiful and I want her to have it." ?
?A rep for Swift could not be reached for comment, and MTV declined to comment.
