Kristin Cavallari is determined to stick a cork in reports claiming she dated John Mayer. The Hills star made on appearance on On-Air With Ryan Seacrest on Tuesday, where she admitted Mayer once asked her out but insists she turned him down.

“I didn’t want to be another notch on his belt,” the 22-year-old told Ryan.

In the past, John Mayer has been romantically linked to Jennifer Love Hewitt, Jessica Simpson, and Jennifer Aniston. Last month, the musician took to his Twitter page to debunk rumors that he was was romancing Kristin, writing:

Rumor control: How do I put this like a gentleman…I have never high fived Kristin Cavalari with my penis.
I have never Bensoned her Hedges, nor have I attempted to Bartle her James.
My Milli has never slam danced with her Vanilli.
I’m sure she’s a wonderful gal but we have never tasted the Skittles Rainbow together.
