sunglasses Kelly Clarkson sur shorts tattoo It looks like someone has been hitting the gym!

We spotted Kelly Clarkson grabbing lunch with a female friend at Sur in West Hollywood yesterday, and we almost didn't recognize the "Stronger" singer... she's lost so much weight!

Maybe it's because the American Idol alum is happy in love with her boyfriend? The 30-year-old brunette beauty has been dating Nashville-based talent manager Brandon Blackstock, who happens to be the stepson of country star Reba McEntire, since last year. Romance is better than Ben & Jerrys any day!

Although, apparently being in a happy relationship is bad for song writing.

"It's ruining my creativity. I'm writing all this happy [stuff]... People are going to be, like, 'What the hell happened to you.' It has been really difficult. I love it. It's an awesome problem to have," she tells People magazine.

Whether she sings depressing or upbeat songs, Miss Clarkson has a voice that will stand the test of time!
