Kris Jenner reportedly spent several days earlier in the month partying in Mexico without her husband, Bruce Jenner. According to Hollywood News Daily, sources close to the reality star said it's common knowledge that whenever Kris is in Mexico things probably aren't going good in her marriage.

Reportedly Kris jetted off to Mexico with her lover, leaving Bruce behind.

"It's a well-known fact that when Kris heads off to Mexico, she is cheating on Bruce," a source said.

The source claims that Bruce knows exactly what's going on and is fed up with the cheating and is ready to get a divorce. It's been rumored for months that Kris and Bruce's marriage was falling apart.

On the family reality show, "Keeping Up With the Kardashians," Bruce bought his own Malibu beach pad and has been spending quite a bit of time there. On the episode, he said he was purchasing it because he needed "a little extra space" but that only fueled rumors that the two were having serious problems.

The source didn't say who Kris' alleged lover is but her first marriage to Robert Kardashian ended because she cheated with Todd Waterman, who has made an appearance on the show. Recently, Kris was spotted without her wedding ring on as she and Kim Kardashian's best friend, Jonathan Cheban, did a little shopping in Los Angeles.

A source told In Touch magazine back in August that the marriage was pretty much over and a divorce should be happening soon.

"They've had problems for a long time and have been separated for months," the source said. "They haven't slept together in years and pretty much just have a business relationship at this point. Their marriage is over."

Kris and Bruce aren't the only ones dealing with a rocky marriage. Khloe Kardashian and Lamar Odom spent their fourth wedding anniversary seperate amid divorce rumors.
