Keyshia Cole is sorely mistaken if she believes she got bumped to make room for a singer named The Weeknd at a concert in Oakland this week — at least according to the San Fran radio station behind the show … because fact is, she wasn’t headliner material to begin with.

Keyshia went off on Twitter Monday night — the same night as KMEL 106’s Holiday House of Soul concert — claiming she bailed on the show because KMEL contacted her last minute to tell her she’d be opening for The Weeknd … instead of headlining the show herself.

She wrote, “EVERY F**KING YEAR I do something major for my city! @KMEL has the nerve to tell me at the last minute they want me to open for the weeknd.”

She added, “No disrespect to the weeknd. Why the hell would @106KMEL ask me to open for him in My home town! Where I give back! Where IM FROM! #NO”

But KMEL tells TMZ, it’s all a case of miscommunication — saying, “We were surprised to see Keyshia Cole’s Tweets the night of our show … as she was never scheduled to be the show’s final act.”

KMEL added, “When we were notified a week before her performance that she planned to cancel, we immediately removed her name from all advertising and promotion and offered refunds to those fans who requested.”

R&B singer Jeremih replaced Keyshia when she abandoned ship.
