"He has had a huge ego boost from hooking up with Kourt. It's been going on for a few months," a source recently told People magazine. "He is used to being swooned by young girls that have nothing else going on. Kourt is a hot mom with a career."
All of this comes after Kourtney and the Biebs were caught being "super touchy feely," at the Nice Guy in West Hollywood last Friday. Kourt's ex (and baby daddy) Scott Disick is reportedly upset by the romance. But Bieber isn't bothered by talk that he is a rebound for Kourtney.
"He more thought, 'Wow,' and couldn't believe that she would go for him," the source said. "He brags about how hot she is. He is happy while it lasts. Even if she is using him to get back at Scott, he couldn't care less."
An insider also told People that something has been going on between Bieber and Kardashian for months.
"He's obviously close to the family, and Kris [Jenner] is obsessed with him," the source said. "It's just one of those things where it makes Kourtney feel good about herself. It's not serious at all. This young guy is into her, he thinks she's hot and she's older. She just wants to have fun."
