Kristin Cavallari may have slept with a major movie star … ’cause her friend shouted out she and Jason Statham hooked up in a viral video trend.

Here’s the deal … Kristin Cavallari and her longtime pal Justin Anderson participated in the “Suspect” trend on social media — the video trend where friends yell out “Suspect is…” followed by brutally honest, often hilarious facts, about one another.

Kristin and Justin’s is no different … with the two trading barbs — including one where Justin says “Suspect’s hottest hookup that she’s never told anyone about was with Jason Statham.”

Pretty cut and dry here … Justin’s saying Kristin and Jason did the deed — though, to be fair, he yells it out during a video trend that’s supposed to be funny.

Worth noting though … Kristin and Jason were romantically linked way back in the day — before she even married Jay Cutler — so, it’s not outside the realm of possibility.

Speaking of Cutler, Anderson seemingly fired a shot at the former Bears QB in the clip too … saying Kristin has “turned all of her ex-boyfriends into alcoholics.” Remember, Cutler was arrested just last month on DUI and gun charges.
