Kris' Heartbreak! Boyfriend Corey Gamble Caught Eyeing Mystery Woman's Butt During Mani-Pedi Session

Kris Jenner's family's scandals over the last year could be the reason for her sudden weight gain, but is the momager, 60, about to face another problem with her boyfriend of two years, Corey Gamble?

Corey, 35, was spotted getting a manipedi at a nail salon in Beverly Hills on June 9, but he didn't appear to be alone.

While Kris' man looked to enjoy his me-time session, he also soaked up some conversation with a skinny mystery woman. But things got heated when she got up to leave her salon chair.

Corey snuck a look at her butt in the process, which could hurt Kris' self-esteem as she continues to suffer with her weight gain nightmare.

So what went wrong for the once-fit mother of six? Insiders close to Kris told Star that she's been stuck in a downward spiral brought on by a series of recent family crises, and she's coped by making severely unhealthy lifestyle choices.

"Kris gained about 72 lbs. in the second half of 2015," a Kardashian source estimated. "It's really sad because she was in the best shape of her life last summer. She had stepped up her workouts and was eating really healthfully, even cutting down the booze. But she couldn't keep it up."

And recently, Kris' boozy disaster was even caught on camera. Do you think Corey and Kris are headed for a nasty split? Tweet us!
