Scott Disick may be moving on from his ex-partner, Kourtney Kardashian.

According to People, the “Keeping Up With the Kardashians” reality TV star was spotted spending time with 19-year-old British model Ella Ross. The rumored couple celebrated Cinco de Mayo on Friday, May 5, and were also seen grabbing lunch at Nobu Malibu the same day.

A source close to Disick told the publication that the reality TV star is unhappy with the fact that Kardashian has started dating other people. “For him, it’s fine to hang out with girls, but when Kourtney does, he pouts. Kourtney doesn’t care what he thinks. She just thinks he is the last person who should have any opinion about who she is dating.

Meanwhile, Disick recently told his ex-partner’s sisters, Kim Kardashian-West and Khloe Kardashian, that he asked her to marry him at one point. However, she refused. “It was really weird. I don’t think we told anybody actually. It was somewhat cute and then we got scared about like, media, this and that. And we were like, ‘Let’s just put the ring aside and we’ll talk about it another day.’ Never spoke about it again,” he said.

Earlier this year, a source told US Weekly that Disick asked for Kardashian’s hand in marriage, but she didn’t say yes. The source added that Disick just asked his ex-girlfriend casually, and he never gave her a ring. “Scott proposed to Kourtney. Not with a ring. He just said, ‘Let’s get married.’ She told him no. Scott was embarrassed, upset and angry,” the source said. The publication also noted that Disick had been on a two-year mission to win Kardashian back, but it just didn’t happen.

Following the rejection, Disick started hanging out with random women. He even flew one woman to the Papagayo Peninsula, and the two of them were spotted by the “Keeping Up With the Kardashians” production team inside the hotel room. A show insider told US Weekly that Kardashian is not upset knowing or even seeing Disick with other women. However, the reality TV star is not pleased with the fact that the patriarch disrupted their trip with their three children, Mason, 7, Penelope, 4, and Reign, 2. “If you’re dating someone important, bring her to meet the family. Don’t hide her,” the insider said.

A recent episode of the hit E! series also saw Disick panicking when Kardashian-West and their friends noticed a woman’s bag inside their hotel room. When she went to the downstairs bedroom, Kardashian-West saw a woman hiding inside the bathroom. On Sunday night’s episode, Disick and Kardashian-West finally had the chance to have a conversation about what he did.

In the end, Disick made it up to his ex-girlfriend by planning a fun trip with their three children. In one of the scenes from the episode, Disick flirted with her by kissing her neck and cheeks. Kardashian didn’t stop Disick from doing so. During her interview, Kardashian said that at the end the day, the most important thing for her is that they are all able to spend time with their children every now and then.
