West's headlining performance, announced on Twitter, was followed by announcements of the other two performers who will close the games July 26.

Pitbull and Canadian singer Serena Ryder will also take the stage at the closing ceremony.

Or, as Stephen Colbert more aptly put it, the ceremony will "feature" Mr. 305.

"I've noticed on a lot of rap songs ... it often says 'feat.' Pitbull. ... I think Pitbull's first name might actually be 'Feat,'" Colbert said.

West's performance was first rumored after Anthony Bennett, member of the Canadian men's basketball team, tweeted about it.
