Khloe Kardashian Fails To Crack A Smile As She Heads To The Gym In Beverly Hills (PHOTOS)

Khloe Kardashian kept her head down and failed to crack a smile as she headed to the gym in Beverly Hills yesterday, following reports that broke over the weekend suggesting that Celebrity Big Brother’s Jasmine Waltz could be behind her and ex hubby Lamar Odom’s marriage “being destroyed.”

Khloe teamed some bright blue trainers with an all black gym outfit for her workout session yesterday, tying her hair up into a bun on the top of her head.

Covering her face with sunglasses, the KUWTK star didn’t seem too happy as she was surrounded by paparazzi.

Could Khloe’s glum face have anything to do with the Jasmine Waltz alleged cheating reports that broke recently?

The Celebrity Big Brother contestant, who is notorious for allegedly being a catalyst behind David Arquette and Courtney Cox’s divorce, is said to have encouraged Odom’s boozy antics, in a tabloid report published over the weekend.

“Jasmine’s known him for about 10 years,” a source told The Sun. “Last year she was spending time with him a lot, partying at hotel rooms late into the night.”

The CBB babe had reportedly been spending lots of time with Odom days before jetting off to England for this year’s Channel 5 reality TV show.

“Eventually she offered to keep him at her house. He moved out just before she flew to the UK for Big Brother. He needed support, but Jasmine encouraged his wild lifestyle,” the insider added.

Waltz has previously been liked to Ryan Seacrest, Jesse McCartney and Chris Pine.
