"It was a pleasure to develop a unique app like Kelly Clarkson Open Mic utilizing the revolutionary features of iPhone and iPod touch," said Andrew Howlett, president of Rain. "Kelly and the RCA team were fantastic to work with and we know fans will love singing along with these great tracks. Good luck staying on key!"

Additionally, fans who register the highest score on Superstar mode for the track Already Gone will be eligible to win a very special prize. The grand prize winner in each US tour market will get the chance to sing Already Gone at Clarkson's soundcheck, win tickets to the show and experience a special meet & greet. One runner up in each US tour market will receive tickets to a concert along with a meet & greet.

"I know my fans are as competitive as I am, and I bet we see some high scores! I can't wait to meet the winners out on the road during my tour," Clarkson said.
