McLean is set to cha cha against fellow celebrities Carole Baskin, Chrishell Stause, Jesse Metcalfe and Anne Heche in the new season of DWTS.

The transformation has been in the works for quite some time. In August, the singer posted a shirtless video and photo of himself revealing his slimmed-down physique on Instagram. “Blood, sweat, tears. Rinse and Repeat,” he captioned the photo. He also thanked his personal trainer Bobby Strom for getting him into dancing shape. “Thank you @bobbystrom for helping me find my body and piece of mind again! This is an ongoing journey that I will never stop working on. Never felt better and more confident about my body and spirit as I do today.”
