John Mayer apparently crashed and burned with The Hills' Kristin Cavallari, who says she declined to date him.
"I didn't want to be another notch on his belt," Cavallari, 22, told Ryan Seacrest on radio station KIIS FM yesterday. Cavallari -- who says she met the singer once briefly -- says Mayer asked her out but she turned him down.
The Hills star also said she doesn't get along with co-star Audrina Patridge.
"I get along with everybody except for Audrina ... I don't like Audrina. I don't think she likes me," Cavallari says.
