Anne Hathaway could moonlight as a karaoke lounge singer if the acting thing fizzles out. The "WeCrashed" star, 39, proved her pipes when she made an appearance on "The Kelly Clarkson Show" Tuesday and beat the "American Idol" winner at her own game of "Sing That Name That Tune" by performing part of one of Clarkson’s big hits. It all started when Hathaway jumped out to a 3-0 lead on Clarkson and the talk show host hilariously tried to get Matt Iseman and her band to "play a fricking song I'll know." On came Clarkson’s 2004 smash "Since U Been Gone." Within seconds, Hathaway stepped up to the center podium and let her voice rip, singing the song’s chorus to the live studio audience.

Kelly Clarkson has set the record straight on the news that she planned to change her name. The singer had reportedly filed documents in February to legally change her name, 20 years after she first found fame on American Idol. PHOTOS: Inside Kelly Clarkson's jaw-dropping $5.4m LA mega-mansion She has been requesting to be known legally as Kelly Brianne, her first and middle names.

Change of plans: Kelly Clarkson, 39, won’t be changing her name now that she’s divorced from Brandon Blackstock, 45. The “Stronger” hitmaker petitioned in February court documents to change her name to Kelly Brianne (Brianne’s her middle name). But on March 21, Kelly revealed to PEOPLE (the TV Show!) that she’s still going by “Kelly Clarkson” — at least in her professional life.

Kelly Clarkson never saw this one coming.

Kelly Clarkson and Anne Hathaway faced off in a singing competition, and the outcome was very unexpected. On the March 22 episode of The Kelly Clarkson Show, the two stars played a game of “Sing That Name That Tune” hosted by Matt Iseman. Kelly, 39, and Anne, 39, stood on opposing platforms as the beginning tune of a song would play, and once they recognized the song, they would step out on the platform and sing the lyrics. Well, after Anne beat Kelly in the first three rounds, the American Idol champion was frustrated things weren’t going her way.

Kelly Clarkson had an embarrassing moment on the latest episode of The Kelly Clarkson Show!

Don’t worry: Kelly Clarkson is still Kelly Clarkson.
