Is there a new man in this momager's life? After Kris Jenner enjoyed a cozy dinner with possible new love interest Corey Gamble at Casa Vega in Sherman Oaks, Calif., earlier this month, the reality star brought him to her daughter Kim Kardashian's birthday party this past weekend.

Multiple sources confirm to Us Weekly that the two have been casually dating recently, though they've known each other for a while.

An observer at Casa Vega tells Us that the two "flirted openly" over dinner in mid-October. The eyewitness adds that Jenner, 58, and Gamble, 34, shared a booth and weren't coy about sitting together in the restaurant — body language included.

"She was leaning in and listening intently to what he was saying," the source tells Us. "She was definitely acting flirty with him and smiling from ear to ear." Another observer tells Us that the mother of six was indeed on a date with a mystery man, later to be confirmed as Gamble.

This past weekend, Gamble — a road manager with Scooter Braun's SB Projects — joined Jenner and the rest of the Kardashian family as they traveled via private jet to Las Vegas for Kim's birthday bash. It seems he didn't have any trouble fitting in with the family, after both Khloe and the birthday girl posted photos including Gamble on Friday, Oct. 24. (Kim and Khloe shared pictures with their large party group on the tarmac of an airport Friday, Oct. 24, shortly after arriving in Sin City.)

Gamble was also photographed arriving at Van Nuys airport early Saturday morning with Kris, and her daughters after a night of partying at Tao Las Vegas. A different source who was at Tao tells Us that the Kardashian family matriarch did not shy away from the PDA with Gamble at Kim's party.

"Kris and Corey were cuddling," the eyewitness recalls to Us, adding that Gamble was quite the gentleman that evening. "He walked her to the restroom," the source says, and "walked her out of Tao." The couple also quietly held hands throughout the night.

Kris' burgeoning new romance comes ten days after her ex, Bruce Jenner, recently stepped out with his rumored new girlfriend — Kris' former assistant and longtime BFF Ronda Kamihira.
