May 8 (UPI) -- Scott Disick was spotted with rumored girlfriend Ella Ross over the weekend.
The 33-year-old American reality star stepped out with the 21-year-old British model Friday in Los Angeles following reports ex-partner Kourtney Kardashian is dating Younes Bendjima.
Disick and Ross were seen leaving TAO restaurant in West Hollywood, according to People. The pair were spotted grabbing lunch at Nobu in Malibu earlier in the day.
"He doesn't like that [Kourtney] is dating," a source told the magazine. "For him, it's fine to hang out with girls, but when Kourtney does, he pouts."
"Kourtney doesn't care what he thinks," the insider added. "She just thinks he is the last person who should have any opinions about who she is dating."
Kardashian, who split from Disick in 2015 after nine years of dating, stepped out with Bendjima, a 24-year-old former boxer, Tuesday in West Hollywood. E! News reported the pair first met during Paris Fashion Week in October.
"Kourtney and Younes have seen each other several times in the last week. It's been casual, but they are really getting to know each other and having fun," a source said.
"Scott doesn't like Kourtney dating Younes at all," the insider added. "He doesn't want to see photos of them or know about it. Kourtney has tried to give Scott a heads up that he might be seeing photos, but Scott can't stand seeing her with someone else."
Disick and Kardashian share three children, 7-year-old son Mason, 4-year-old daughter Penelope and 2-year-old son Reign. The pair enjoyed a family trip to Aspen in January before Kardashian's sister Kim Kardashian caught a woman in Disick's hotel room.
