The matriarch of the Kardashian/Jenner clan Kris Jenner celebrated her 59th birthday in Las Vegas with her new beau Corey Gamble.

The duo, along with Scott Disick, were seen partying at the Las Vegas’ 1 Oak nightclub on Friday, November 7. “She and Corey were very smitten with one another,” an insider told Us Weekly. The onlooker added that the couple took plenty of selfies together and at one point Gamble gave Jenner a kiss on the cheek before leaving the club at around 2:00 a.m.

Kris split from her husband of 23 years, Olympic gold medalist Bruce Jenner, earlier this year. Khloe Kardashian, Kris’ daughter, confirmed her mother’s relationship with Corey, making this the first boyfriend Kris has had since leaving Bruce.

Khloe said that Kris is very happy and the whole family loves Corey. “Corey was over last night and he’s great. I love him,” Khloé said. “He’s so sweet and my mom is really happy.”

“I like to see her in such a positive, happy state,” Khloé added. “It’s a good Kris Jenner.”

And, as for Kris, she said her relationship is wonderful. “It’s just a big family thing right now,” the Keeping up with the Kardashians star told Us Weekly. “Everything is wonderful.”

While the rest of her family wasn’t present during the festivities in Las Vegas, they still took the time to wish their mom a very happy birthday.

“Happy Birthday to my best friend in the entire world!!!!” Kim Kardashian wrote in an Instagram post alongside a picture of her and Kris. “After becoming a mom myself I understand you in a way I didn’t think was possible! I respect so much how you are able to raise 6 children, have a career and give each of us so much attention and be our biggest supporter and love us so unconditionally!!! You are my idol, my mentor and superwoman!!!! I love you forever!!!!”
