Scott Disick and Sofia Ritchie have split up after nearly three years together, it's claimed.

The pair's romance had "run its course" and Sofia was reportedly "fed up" with Scott's behaviour.

There is a 16-year age gap between Scott, 37, and 21-year-old Sofia.

It's also claimed that the Scott's closeness to his ex Kourtney Kardashian, with whom he shares Mason, 10, Penelope, seven, and Reign, five, wore Sofia down.

He split from Kourtney, 41, in 2015 and began dating Sofia in 2017.

A source told Page Six : "Kourtney didn’t make it easy for he and you can only tolerate that kind of treatment for so long."

Scott checked into rehab in April but checked out just a few weeks later.

He has battled substance abuse and has struggled to cope with the grief of losing his parents.

And it's claimed his recent behaviour contributed to the split.

He celebrated his birthday this week and received gushing tributes from Kourtney's family.

Her mum Kris Jenner even less than subtly hinted that she wanted them to get back together.

It remains to be seen if a reunion is now on the cards.
