Kris Jenner and Corey Gamble may be on the rocks.

According to a new report, Gamble, 35, was caught with another woman this week in Los Angeles as the 60-year-old Keeping Up With the Kardashians star was away.

"That's not Kris Jenner's booty! Corey Gamble was spotted engaging in some suspicious behavior while his leading lady was away!" OK! Magazine reported on Friday. "The 35-year-old pampered himself with a manicure and pedicure as he spoke with a mystery lady. Corey dressed casually for the outing in a white shirt and black shorts."

Jenner began dating Gamble shortly after her divorce from former husband Bruce Jenner, who has since proclaimed his female identity and goes by the name Caitlyn.

This isn't the first time Gamble has been accused of spending time with other women behind Jenner's back. In January, Gamble was seen with a bevy of women in St. Barts.

One month later, Jenner was said to be considering replacing her boy toy.

“Kris and Corey’s romance has really been ramped up – it’s mostly for show and more of an employer/employee scenario,” a family insider told Radar Online in February. “He’s under contract and it’s due for renewal in the next few months and no one thinks she’s going to keep up this particular appearance.”

The report went on to claim Jenner was “actively looking” for another younger man to replace him and was doing her best to get in shape before doing so.

“Kris has been madly working out and losing the 15 lbs. she put on over the holidays,” said the insider of Jenner’s pre-breakup plan. “Poor Corey has no idea, but she’ll make sure he leaves with a nice big payout that keeps him quiet.“
