Kris Jenner Keeps a Watchful Eye on Corey Gamble After Partying In Vegas With Jessica Alba

Kardashian momager Kris Jenner is burning with jealousy, say insiders, after learning that her boyfriend Corey Gamble was partying Jessica Alba at a Las Vegas event.

Sources say the 69-year-old Kris sees the 44-year-old Hollywood actress as a rival following Corey’s very friendly encounter.

“She’s telling Corey to explain himself, but the fact is he made her look like a fool and nothing he says will calm his girlfriend down,” says an insider.

Trouble exploded after Kris’ 44-year-old boyfriend was spotted flirting with the Sin City star at the opening of the Palm Tree Beach Club at MGM Grand.

Photos show the talent manager and the brunette beauty in a corner and whispering something in her ear that caused her to rock back her head in laughter.

“Corey was clearly making a play for Jessica. Kris could tell he was,” says the insider.

Sources tell GLOBE the reality show matriarch feels Jessica is competition for her much-younger man.

“Jessica’s friends are saying she was just being polite and gave no indication she was going along with it or interested in Corey, but Kris is still jealous of her,” says the insider.

According to the source, Kris is aware that Jessica is free as a bird following her split from husband Cash Warren in December after 16 years of marriage and kids Honor, 16, Haven, 13, and Hayes, 7.

Sources say, “Kris expects Corey to behave and act like a kept man, not a single guy.”
