Kristin Cavallari is shooting down rumors that she had a fling with Kourtney Kardashian’s baby daddy, Scott Disick, several years ago.

in fact, she thinks the Kardashian’s are disrespectful for planting the story!

“First of all, it’s 100 percent not true,” Kristin told Access Hollywood. “I just think, what convenient timing for them with their show premiering next week and with everything that’s going on with Kim Kardashian, I feel like they’re trying to take the heat off her.”

In Life & Style’s new issue, the mag claims Kristin and Scott hooked up several years ago, before Kourtney became pregnant with Mason.

Kristin suggested that the timing of the story was too close for comfort, seemingly putting the blame for the story on the Kardshian 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.

You know, it wouldn’t surprise me one bit if the Kardashian’s planted the story.
