Sofia Richie finally ends things with Scott Disick after being cheated on severally..

It seems the unlikely romance between Sofia Richie, 19, and Scott Disick, 35, is over!

According to an Us Weekly source, the duo split up after an infidelity forced Sofia's famous musician father Lionel Richie to step in and put and end to what he called a toxic relationship

'Sofia and Scott split up,' a source told the publication, adding 'he cheated on her in Miami and she found out and told Lionel.'

 The legendary recording artist then reportedly said 'he is going to cut Sofia off and write her out of his will if she continues her relationship with Scott as he thinks he’s extremely toxic for her.'

Apparently the aspiring model learned about the Miami cheating incident, 'after their trip to St. Bart’s and it caused huge problems in their relationship' the source explained.

 The same source also confirmed 'he went to Wyoming because of it and was photographed with another girl and that was the icing on the cake for her to break up with him.'

Sofia and Scott had been 'trying to work things out,' but the photograph triggered Lionel to forbid them continuing to see each other.

 It seems the episode has crystallized the situation for Sofia, who is now 'leaning towards sticking with her family and Lionel because she realizes the severity of it.'

The news of the breakup is not surprising, given that Sofia looked downcast as she was snapped in Beverly Hills, California on Friday amid news her boyfriend Scott Disick was seen in a passionate embrace with another woman while attending Kanye West's album launch party in Wyoming the previous day.  

While Sofia was at the Nobu location in Malibu, California, a favorite haunt for the Kardashian family, the 35-year-old Disick, who has three children with ex Kourtney Kardashian - son Mason, eight, daughter Penelope, five, and son Reign, three - was in the Midwest in the romantic embrace during West's bash on Thursday, overheard saying he was 'single,' according to TMZ.

The unexpected development came less than a week after Scott and Sofia took a romantic trip to the Caribbean paradise of St. Barts to celebrate his recent birthday. 

Sofia and Scott have been together since the summer of 2017, and made their relationship Instagram official last September but have now gone their separate ways..
