Scott Disick's Full Girlfriend List After ‘Kardashian’ Star Brings Chelsea On Family Trip

“Keeping Up With the Kardashians” star Scott Disick shocked his pseudo in-laws when he brought another woman to their family vacation to Costa Rica on Sunday’s episode of the hit E! reality show. He and Kourtney Kardashian, the mother of his three children, famously have a tumultuous relationship. As rumors swirl about his current significant other, check out a full girlfriend list since he and Kardashian split in 2015 year after nearly 10 years together.

1. Ella Ross — Present: He and Ross, a 19-year-old British model, were photographed at Nobu restaurant in Los Angeles Friday, Us Weekly reported Sunday. They were spotted together at TAO Asian Bistro later that night.

2. Christine Burke — March 2016: Lord Disick and Burke, 21, were pictured at Nobu in Malibu, Us Weekly wrote in a different article. They were also seen around Los Angeles. At the time, some claimed the model looked like Kourtney’s half-sister, Victoria’s Secret model Kendall Jenner.

3. Chloe Bartoli — July 2015: Being photographed with Bartoli, his ex-girlfriend, is what reportedly led to the end of his relationship with Kourtney, even though they were always on the rocks. Disick and Bartoli got caught together in the South of France in July of 2015. The two first dated in 2006 when he and Kourtney were on a break.

“He was hot and heavy with Chloe for a brief time,” a source told Us Weekly at the time. “This is a person that Kourtney has asked Scott many times to not speak to or hang out with.”

They apparently kept in touch over the years. “This has been going on forever,” a source said to the publication in 2015. “They would meet up in NYC. I heard about it first at least a year ago. Chloe is sweet but loves running in these celebrity circles.”

4. “Chelsea” – January 2017: When it comes to the mustery woman woman Lord Disick brought to Costa Rica, the Kardashians identified the new woman as “Chelsea” on Sunday’s episode. Sister Kim and Khloé overtly hinted they knew about the secret woman.

Kim said aloud, “Did you guys hear what Chelsea said?”

“Oh, yeah,” Khloé responded. “She's such a bitch.”

“No, she was so nice,” Kim answered.

“She was a bitch,” Khloé said again.

“Oh, Chelsea Handler . No, no, no, I'm talking about Chelsea Clinton , what she said when she was sticking up for Barron Trump ,” Kim replied.

“That's nice that Chelsea did that,” Khloé said. “But I thought you meant Chelsea Handler.”

Finally, Kim was ready to addressed Disick and said “cut the shit.” Kourtney — who is the mother of Mason, 7, Penelope, 4, and Reign, 2 — sat there silently. But he didn’t have a chance to answer during the episode because the performers came out.

“It's pretty obvious that the girls know something's up,” he admitted, seemingly aware he was caught with someone else. “Nobody really wants to say what's on their mind and if this dinner isn't awkward enough these fire dancers have to come out and start doing hula hoops. I already felt like under fire.”
