On 'Lopez Tonight' (weeknights, 12AM ET on TBS), Prince opened up about all the covers of his songs and an industry loophole that "doesn't exist in any other art form -- be it books, movies..."

"I don't mind fans singing the songs. My problem is when the industry covers the music," he said. "A lot of times, people think I'm doing a Sinéad O'Connor song ['Nothing Compares 2 U'] and Chaka Khan songs, when in fact I wrote those songs."

The list of singers agreeing to appear on FOX's Duets, a contest that pairs regular celebrities with singing celebrities, is a mixture of has-beens, legends, and Michael Bolton. The singers are: Cyndi Lauper, Smokey Robinson, Chaka Khan, Clint Black, Dionne Warwick, Patti LaBelle, Brian McKnight, Macy Gray, Kenny Loggins, Richard Marx, Randy Travis, and Aaron Neville. That's actually a pretty impressive list. I think many of those singers have done guest appearances on American Idol.

Now... who would make an interesting pair? I wouldn't be surprised to see Nicollette Sheridan coupled with her fiance, Michael Bolton. How about Punky Brewster with Cyndi Lauper? And Johnny Fairplay with Macy Gray?

The series debuts August 29th. The celebrity pairs will be eliminated each week by judges and viewer votes.
