"Kourtney's like a dear friend. That's it," he said. "I mean, I love her to death. I love her family to death. But yeah, just friends."
The musician was joined on the red carpet by his three children: daughter Alabama, 13, and son Landon, 15 -- who he shares with ex-wife Shanna Moakler -- and stepdaughter Atiana, 19, Shanna's daughter with Oscar de la Hoya.
As for Kourtney, she's busy juggling three kids of her own: son Mason, 9, daughter Penelope, 6, and son Reign, 4, who she shares with ex-boyfriend Scott Disick.
While Scott is still going strong with girlfriend Sofia Richie, Kourtney is seemingly enjoying the single life after parting ways with Algerian model Younes Bendigma last year.
After nearly two years of dating -- and a super-long Italian vacation -- Kourtney dumped the 25-year-old. The two reportedly started having problems as soon as they got back from Europe, but when Younes was photographed getting cozy with an Instagram model in Mexico, that's when Kourt pulled the plug. Younes didn't handle the breakup well and went off on "the media" in a series of Instagram Stories.
But TMZ reported that the two ran into each other at Alfred Tea on Melrose Place just last month and that they seemed to be on good terms. The person who snapped the photos said Younes was in line ordering when Kourtney and her friend approached him. Kourtney and Younes reportedly got handsy with one another, and she kissed him on the cheek when they said goodbye.
