Kris Jenner has all eyes on her once again. The "Keeping Up With the Kardashians" star is hooking up with Ben Flajnik because of their "sexual chemistry," according to a new report. 

Things may have heated up between Jenner and Flajnik, who reportedly went on vacation to Cabo San Lucas, Mexico.

Sources told Hollywood Life  that the the twosome kissed several times during the trip, and have a "full-blown" romance. With Kim, Khloe and Kourtney Kardashian's mother separated from Bruce Jenner, it seems as if she is enjoying life with the younger "The Bachelor" alum. 

But the momager has been tight-lipped about having the hots for Flajnik despite the speculation about her budding relationship. 

The pair have been shy about talking about what they mean to each other. But Kylie and Kendall Jenner's mom did put a photo of her new male "friend" on Instagram on Dec. 3. She captioned the image, "Date night with @benflajnik and @lizheinlein." 

Despite the twosome' denial, many reports said they are more than pals.

"When they went to Mexico, they were all over each other," said the source to HL. "They were hooking up the entire time and not hiding it at all."

Another source told the celebrity news site that they have "crazy sexual chemistry" and that Ben is just "in awe" of Kris.

"Ben likes the fact that Kris is not needy," said the second source."She's fun and young spirited. Kris likes that Ben is so adventuresome, not to mention sexy and sweet. They both want to spend New Year's Eve together and just have fun. Do something crazy together to bring in the new year with a bang!"
