Kris Jenner's marriage to Bruce Jenner is on the rocks after her husband of 21-years caught her attempting to hook up with her ex. As shown in recent episodes of "Keeping up with the Kardashians," Kris' ex-boyfriend, Todd Waterman, tried to rekindle the flame by setting up a date with the momager. 

Things first started getting rocky when Bruce walked in on Kris writing an email to her former lover, who is said to be the reason she divorced her first husband, Robert Kardashian. In the show, it shows Kris bumping into Todd, at a Los Angeles tennis club, where she gave him a long passionate hug and exchanged contact information. Later on, they show Kris on her way to meet Waterman, but backing out at the last minute. However, according to Radar, sources have confirmed that she did actually go on a date with Waterman, despite how it is portrayed on air.

"Kris told no one, but she did go out with Todd, and it was an electrifying date," said an insider to the National Enquirer. "Kris walked out of the restaurant where they'd met looking like the cat that ate the canary. It's so obvious that she still carries a torch for him."

According to the source, Bruce does not take cheating lightly and strongly believes that once a cheater always a cheater. He is deeply betrayed that Kris would even consider going on a date with Todd when their relationship is already on the chopping block.

"Cheating is a deal breaker for him, so their marriage is teetering on the edge. Bruce would feel totally betrayed if he actually knew the length and breadth of Kris and Todd's current relationship. They had continued to feverishly e-mail each other, flirt and text," the insider revealed.

Bruce is said to be at his wits end, and has lost a massive amount of trust and faith in their relationship.

"I think Kris is covering up a lot of secrets and lies.. Bruce's feelings are still raw... I don't think he can take much more, and will be wondering what else Kris is up to behind his back."
