CLEVELAND -- Did you hear the excited screams late Sunday night?

Because the Cleveland Cavaliers swept the Detroit Pistons, Justin Bieber’s concert at Quicken Loans Arena is moving forward as scheduled Tuesday night.

Whew...

Had there been a need for game five, Bieber's Purpose World Tour stop could not have taken place at The Q due to the playoffs.

We're told there was a contingency plan in place, which could have included either moving the Biebs to a different venue or rescheduling the performance entirely.

Ironically, Bieber will take the stage Monday night in the Palace of Auburn Hills, which is the exact arena where the Cavs completed their round-one sweep.

After his Cleveland concert, Bieber heads south for a show at the Schottenstein Center in Columbus on Thursday evening.
