Scott Disick and Sofia Richie have ended their relationship, according to a new report.

UsWeekly reported Wednesday that the pair have called it quits after almost three years of dating. 

Rumors that the pair had split have been rife for weeks now since Scott, 37, entered rehab, seeking treatment for 'past traumas' while Sofia, 21, has been spotted in Malibu enjoying herself with friends. 

Soon after news broke of the split, Scott shared a photo to Instagram of himself in Utah by a swimming pool. 'Little water never hurt nobody,' remarked the star.

Page Six added that his bad ways and his ex gave Sofia pause. 

'Scott had gone back to his old ways,' the source said, 'and Sofia got fed up.'

And quarantining separately was not easy. There was also an issue with Kourtney. 

'Kourtney didn’t make it easy for her,' the source claimed, 'and you can only tolerate that kind of treatment for so long.' 

Scott recently celebrated his 37th birthday without Sofia, and instead was joined by ex Kourtney Kardashian and their three children, Mason, 10, Penelope, 7, and Reign, 5, in Lake Powell, Utah. 

DailyMail.com revealed exclusively that Scott had checked into rehab on April 28 at the All Points North Lodge in Edwards, Colorado. 

The Talentless CEO was reportedly dealing with issues related to alcohol and cocaine use, but his lawyer Marty Singer disputed that characterization to TMZ. 

'In an effort to finally come to terms and deal with the pain that Scott has been silently suffering for many years due to the sudden death of his mother, followed by the death of his father 3 months later, Scott made the decision to check himself into a rehab facility last week to work on his past traumas.'

Scott, who is from Long Island, New York, saw his mother Bonnie die in October 2013. His father Jeffrey passed away months later in January 2014.

Following his rehab stint, the reality star returned to quarantine together with Sofia.

His ex, Kourtney Kardashian, seemed to reference his rehab stint with a cryptic Instagram Stories post: 'kinda tired of being OK with things im not okay with.'

Scott and Sofia began dating in the summer of 2017. 

Interestingly the pair met around the time of his birthday, as Scott was pictured flirting with Sofia aboard a yacht in the South of France on May 24 for his 34th birthday getaway party. 

By September 2017, it was reported that they were indeed dating, and were pictured in Miami posing in front of a cake that read: 'Congratulations Scott and Sophia [sic].'

Lionel Richie told UsWeekly at the time that he was 'scared to death' about his youngest child being in a relationship with a man 15 years her senior.
