Talk about timing.

Drake bailed on what's arguably the second-most important night in the music business, the Grammy nominations concert, which is tonight, TMZ reports.

"Unfortunately, due to scheduling complications, Drake will no longer be performing ... [he's] currently in the middle of his nationwide 'Would You Like A Tour?' and sincerely apologizes to his fans that he can't be there," a rep told TMZ.

Drake was one of the biggest acts the nominations concert has been promoting, so what could his "scheduling conflict" be? He doesn't have a show tonight, so that's not the culprit.

The rest of the performers are still on track, including Katy Perry, Taylor Swift and Lorde, who were added to the lineup yesterday.
