kristin-cav-denies-scott-ru.jpgKristin Cavallari is denying reports that she hooked up with Scott Disick, and the former Hills hottie told Access Hollywood, “First of all, it’s 100 percent not true. I just think, what convenient timing for them with their show premiering next week and with everything that’s going on for Kim [Kardashian], I feel like they’re trying to take the heat off her.”

Life & Style claims Kristin and Scott hooked up several years ago, and the reality starlet told Access' Billy Bush that the timing of the story was a little too coincidental, hinting that the rumor may have been started by the Kardashian clan! “When there’s a big story like that, they always call you and ask if you want to comment and clearly none of them denied it, so it’s very ... it’s really disrespectful to me and I’m in a committed relationship. It’s disrespectful to me and Jay [Cutler] and I think it just says a lot about their character,” Kristin told Billy.

A source close to the Kardashians called Kristin’s suggestions “absurd," adding, "Like they need publicity?” Who knew Kristin and the Kardashians weren't fans of one another? Meow!
