Grandpa Corey? Five days since Kris Jenner’s milestone 60th birthday, her boy toy, Corey Gamble, turned 35 on Tuesday, Nov. 10, and her eldest daughter, Kourtney Kardashian, took to social media to tease him about it. 

“Happy Birthday @coreygamble ! A grandpa never looked so good,” she captioned a photo of Gamble (who is a year younger than her) with her children Penelope, 3, and Mason, 5. (She is also mom to son Reign, 11 months, with ex Scott Disick.)

Gamble has been linked to Jenner, 60, for more than a year. He was her first real relationship after her 2013 split from Caitlyn Jenner. The pair have been frequently featured on the family’s reality series, Keeping Up With the Kardashians

On the last season of the show, Khloe Kardashian grilled her mom’s new beau on his past, asking him if he’d ever been to jail. 

"Nah," he replied. "I ain't Mr. Perfect, but no trouble that's a disrespect or a threat to another person."

The momager also took to Instagram to wish her man a happy birthday, writing, “Happy Birthday to this amazing man @coreygamble ! I love you baby I hope you have a magical year!!!!!”
