We guess it runs in the family.
In a teaser clip for an upcoming episode of "Keeping Up With The Kardashians," Kris drops the bombshell on the family, after Bruce scolds Khloe for telling his 17-year-old daughter, Kendall, about the racy photos she recently took for her husband, Lamar, in which she posed in a latex catsuit.
"Uh Khloe, do you really think you should be having this conversation with a 17-year-old? I'm all for spicing up a relationship, but ..." Bruce says before he's interrupted by Kris, who asks, "You are?"
He continued, "I'm just saying, especially in this family, photos leaking, this and that, look at the problems it’s caused."
And that's when Kris revealed to her family, "Bruce and I did a video."
"Exercise video, honey,” an absolutely mortified-looking Bruce tried to claim, but Kris just wouldn't drop it.
“Bruce and I made a sex tape," Kris tells the whole family, who will now need more years of therapy than they already do.
At least Bruce claims that they erased it immediately, but we wouldn't be too surprised it that's the next "leaked" video scandal the family is facing.
