Kourtney Kardashian is bouncing back from her younger model ex Younes Bendjima, 25, with an even younger catwalker.

Sources tell us Kourtney’s fallen for 20-year-old Luka Sabbat.

“Kourtney and Luka are dating. They flew into Chicago together over the weekend and were hanging out. He’s been a family friend for years, and they really like him. She likes young boys!” a source said.

Kardashian, 39, and Sabbat were spotted canoodling at a grand-opening bash for the Found Hotel Chicago.

“They were holding hands and smiling by the DJ booth. She seemed very into him and happy. They left together,” a source said.
