Celebrity Fight Night 2012: Reba & Rascal Flatts Put Up Their Dukes for a Good Cause

Country stars Reba McEntire and Rascal Flatts joined several Hollywood heavyweights converged on the J.W Marriott Desert Ridge Resort & Spa in Phoenix, Ariz., last weekend for Muhammad Ali's Celebrity Fight Night XVIII. The annual black-tie event, held by the Celebrity Fight Night Foundation, a non-profit organization founded in 1994 by Jimmy Walker, netted $9.1 million this year in the fight against Parkinson's disease.

Funds raised at this year's star-studded gala go to the Muhammad Ali Parkinson Center at Barrow Neurological Institute in Phoenix, as well as several other worthy charities. Reba, who emceed the event, and Rascal Flatts were among those honoring boxing legend Muhammad Ali (also in attendance), who continues his long personal battle with Parkinson's. Others in attendance this year were Lionel Richie, Tom Hanks, Billy Crystal, Bo Derek, retired NFL quarterback Kurt Warner, Jordin Sparks, Miley Cyrus and her 'Hunger Games' star boyfriend Liam Hemsworth.

"He's a super person, he gives, he's smart," Reba said of Ali. "I sat next to him at the Founder's Dinner [Friday] night and he's still just as sweet as he could be. I just love hanging out with him."

With a host of live musical performances and unique auction items, Celebrity Fight Night has raised more than $70 million in the past 17 years. Reba was the evening's emcee for the seventh consecutive year, with acclaimed producer David Foster serving as Musical Director for his 13th year.
