Khloe, whose new spin-off with sister Kourtney, Kourtney & Khloe Take the Hamptons premiered on Sunday, invited her mom, 58, and her beau, 34, over for a premiere party at her house. Kim Kardashian and husband Kanye West also joined the trio, as well as their daughter North West and Kylie Jenner.
"Khloe thinks Corey is great and so sweet," the source tells Us. "She loves him and loves how happy Kris is."
Jenner has been caught getting cozy with Gamble, a road manager with Justin Bieber's manager Scooter Braun's SB Projects, since last month. After sharing an intimate dinner at Casa Vega mid-October, Gamble then joined the momager in Las Vegas for Kim's 34th birthday party on Friday, Oct. 27. The couple then jetted off for a little R&R in Mexico at the end of the month.
Another source tells Us that Kris and Gamble headed to family friend Joe Francis' home Casa Aramara in Punta Mita to meet the Girls Gone Wild founder's newborn twin daughters. "Kris brought all these amazing gifts with her for the girls," the insider said.
Kris exclusively confirmed to Us that she had separated from her husband of 23 years, Bruce Jenner, in October 2013. On Sept. 22 the cookbook author filed for divorce from the former Olympian.
As previously reported by Us, Kris isn't exactly happy with her estranged husband. A source told Us that she's "livid" that Bruce recently stepped out with her former assistant and friend of 20 years, Ronda Kamihira.
