Rob Kardashian has had one heck of a run, tangoing his way to the Dancing With the Stars finals on ABC this fall. Along for the ride in the audience? His entire family.
Absent until October 31 was Scott Disick, Kourtney Kardashian's baby father. That's 'cause Kristin Cavallari was still on the show until then, Life & Style says.
The celebrity gossip magazine alleges that just before Kourtney became pregnant with her and Scott's child, he was putting it to Kristin, a DWTS hopeful this fall.
"While Kourtney and Scott were on a break, Scott hooked up with Kristin," a friend reveals. "Kourtney can't stand her now and didn't want Scott at show tapings."
A Kardashian pal confirms that "Scott and Kristin definitely hooked up in Las Vegas during a time [February 2009] that he was on a break from Kourtney."
The Kardashian insider adds that both Kourt and Scott were BFFs with Kristin Cavallari, who used to date Kourtney's stepbrother Brody Jenner, at one point.
That was then, though, and this is now.
She and Kristin have been enemies ever since. "Kourtney was furious," the friend says. "She and her sisters have called Kristin 'the whore bag' ever since."
The most surprising part of this report? That Scott Disick actually scored with both of these girls. Look at him, wearing sunglasses at night! What a douche.
