On Friday, Nov. 7 "Keeping Up with the Kardashians" Matriarch Kris Jenner kicked off her 59th birthday celebration with dinner at Las Vegas' Sin City Stack followed by a night of partying at Mirage's 1 OAK, People reports.

Although the entire Kardashian clan was not in attendance for Jenner's birthday festivities, Perez Hilton reports that Jenner posed with cardboard cut outs of various members of the infamous reality-TV family.

Guests who actually arrived to celebrate Jenner's 1 OAK party included Scott Disick, Alec Monopoloy, Jonathan Cheban, and Jenner's new boyfriend, Corey Gamble, says Perez Hilton.

Both Gamble and Jenner -- who were recently spotted coming back from vacation together -- were allegedly "smitten" with one another during the birthday celebration, according to Us Weekly.

"The couple took plenty of selfies together and Corey at one point gave her a kiss on the cheek," said an Us Weekly source.

Jenner also gushed about her new relationship with Gamble to People.

"It's definitely different. It's kind of crazy, in a very good way," she said about her new romance.

Although Kris recently filed for divorce from her long-time husband, Bruce Jenner, it seems that she is quite happy with her family life.

"I'm so blessed with my family. I'm really excited about the holidays and the baby -- Kourtney is having a baby and it's just really great. We enjoy spending time with each other and having fun," Kris told Us Weekly during her birthday celebration.

Another member of the Kardashian family who is equally excited about Kris' relationship with Gamble is Khloe Kardashian.

During a separate interview with Wonderwall, Khloe gave her seal of approval on Kris' new beau.

"He's just a really good person. And I just like to see my mom happy, so it's a good thing to see," she said.
