Scott Disick Cheated On Kourtney Kardashian With Sisters? Disick Bragged About Sleeping With Khloé Kardashian, Kylie Jenner

Scott Disick bragged to his friends of sleeping with Khloé Kardashian and Kylie Jenner, while he was in a relationship with Kourtney Kardashian, according to a report. However, Gossip Cop debunked the claim, saying that the report is “nonsense.”

According to Life & Style magazine, Disick admitted to Kourtney about his “years of cheating” and “drug-fueled sex parties,” when she visited him in rehab earlier this month. A source reportedly told the magazine that he did not tell Kourtney about his close relationship with her two sisters.

The magazine claimed that Disick told his friends about “having sex with Khloé in a Hamptons hotel shower” in 2014, and also sleeping with Jenner “during a drunken night” earlier this year.

Earlier this month, reports surfaced that Kourtney visited Disick in a Malibu rehab center along with her two older children, Mason, 5 and Penelope, 3. Disick has been undergoing treatment at the Cliffside Malibu center since early October.

“She is pleased that he is taking care of himself for the kids' sake -- that he cares enough about the kids to finally deal with his problems,” a source told People magazine. “Kourtney will continue to be supportive as long as Scott stay in rehab. There are talks about at least 90 days.”

Meanwhile, rumors surfaced Tuesday that Disick checked out of the rehab after he posted a photo to his Instagram account of himself boarding a private jet.

Meanwhile, Radar Online reported, citing a source that the 32-year-old was “forced” back into the rehab by the Kardashian clan.

“Scott is now back in the treatment center in Malibu. Kris Jenner told him that, if he did not go back, he would never see his children again,” the source told Radar Online. “If Scott messes up one more time there is absolutely no chance at any sort of reconciliation.”

“Kourtney will get full custody of those kids and she will also do everything that she can to prevent him from even seeing them without her being present,” the source added, and so “Scott made a promise to Kris and to Kourtney, as well as to her whole entire family, that he was going to stay sober for his children and because he loves her.”

However, E! News reported that Disick did not end his fourth rehab stint, and he posted the picture as he is able to use his cell phone.

“Scott has made an effort to cut bad influences out of his life. He knows a lot of people were using him. At the time, he didn't really care because he was caught up in all the partying, but he's finally realized the party has to stop," another source told E! News. "He's focusing on a tighter, more loyal circle of friends -- the people who were there for him before all the money and fame."
