Kourtney Kardashian Is 'Head Over Heels' For 20-Year-Old Luka Sabbat

Kourtney and Luka were spotted at the opening of TAO in Chicago. They were with the reality TV star's friends Malika Haqq and Jonathan Cheban.

While Kourtney and Luka didn't show a ton of PDA, according to onlookers, “they were close to each other, and there was a sense of chemistry as the two were laughing and having fun together all night.”

"All of their friends know she’s head over heels for Luka," an insider told People. "None of her friends liked [her ex-boyfriend] Younes [Bendjima], and they all love Luka even though he’s only 20! They think he’s good for her, and he’s a very down to earth and good guy."

Kourtney and longtime boyfriend Younes broke up last month. The couple was having some issues, particularly with Younes trying to control the sexy pics Kourtney posts to Instagram.

While Kourtney is head-over-heels with her new man, her ex and baby daddy Scott Disick thinks she's trying to "one-up him" by dating a 20 year old. He's currently dating 20-year-old Sofia Richie.
