Mariah Carey Overwhelms Kelly Clarkson

American Idol winner Kelly Clarkson was so nervous when she met real life heroine MARIAH CAREY she feared she was going to vomit on the sexy singer.

Former cocktail waitress Clarkson is a huge fan of the Honey hitmaker and was overwhelmed when Mariah offered her travel tips for her current trip to London.

Kelly swoons, "I completely dorked out. I never get jittery on stage, I don't think I've ever been nervous my whole life, but when I met her I felt like I was gonna be sick through nervousness. She's just such an amazing talent.

"She asked me what I was doing and I said I was coming to London and she was like, 'Oh, you'll love it, I loved it myself.' She's very nice, very sweet and down to earth, and I'm thinking, 'Mariah Carey, why are you talking to me?'"
