So True? So False? Is Kim Kardashian Dating Mark Sanchez?!

Kim Kardashian, already found her rebound romance? Rumors have been circulating that Kim Kardashian has a new man in her life: New York Jets player Mark Sanchez..

Cool down, people. This rumor is so false!

"Dating rumors are always fun when you don't even know the people [you're] supposedly linked to," Kardashian, 31, tweeted Friday. "Who makes this stuff up?"

As for 25-year-old Sanchez? Well, this isn't the first time he's been stuck like this with a star. This past summer, he was rumored to be dating Hayden Panettiere. In reality, however, the actress was lovestruck with Sanchez's teammate and BFF Scotty McKnight.
