John Mayer really wants to stress that he hasn't hooked up with Hills hottie Kristin Cavallari.
In a series of silly Twitter posts, the singer, 31, debunked Internet gossip Wednesday.
"Rumor control: How do I put this like a gentleman...I have never high fived Kristin Cavalari with my penis," read his first post.
He then added, "I'm sure she's a wonderful gal but we have never tasted the Skittles Rainbow together."
Just to make sure he got his point across, he Twittered again, "My Milli has never slam danced with her Vanilli."
