(NEW YORK) -- Former American Idol judge Kara DioGuardi is lining up some top talent for her new reality competition show Platinum Hit, debuting on Bravo May 30.
Billboard reports that Leona Lewis, Natasha Bedingfield, OneRepublic's Ryan Tedder and Donna Summer will all serve as guest judges for the show.
As previously reported, the show features 12 aspiring songwriters who have to compete in challenges, with DioGuardi, who's written a string of hits for the likes of Kelly Clarkson and Celine Dion, acting as head judge. Jewel will host the show and give the contestants feedback. The winner receives $100,000, a publishing deal and a recording deal.
The contestants for the show have also been announced and USA Today reports that at least two of them previously appeared on DioGuardi's old show -- American Idol. They include Jes Hudak, who made it to the Hollywood round in season five, and Jackie Tohn, who was a top 36 semi-finalist in season eight, Dioguardi's first year as a judge.
