Scott Disick 'Devastated' After Girlfriend Sofia Richie Kicks Him To The Curb!

Scott Disick and Sofia Richie's year-long romance ended in disaster this weekend after a blowout fight, and RadarOnline.com has exclusively learned the father of three is "devastated beyond belief!"

According to a source, the 19-year-old daughter of music icon Lionel Richie pulled the plug on their relationship after she caught him cozying up to another woman while at Kanye West's album listening party in Wyoming on May 31.

"Sofia confronted Scott when he returned, and she told him that she was done. She packed up her things and moved out of his house. She told him that he will never find another woman who loved him the way that she loved him!"

Disick, 35, didn't take the news very well. The source said he "begged Sofia to stay," and blamed his bad behavior on booze.

" Scott has been contacting her nonstop and pleading with her to give him another chance," the source continued. "But she is not going to go there. She is staying with her father right now, and Lionel won't let Scott anywhere near his daughter."

As fans know, this is not the first time The Lord ruined a relationship over his two-timing ways. After cheating on baby mama Kourtney Kardashian, 38, with ex Chloe Bartolli in the South of France in 2015, he went on a drug-fueled downward spiral.

Now, friends fear he is headed down a bad path once again.

"Scott is likely going to use this as a reason to go and get all messed up again, and everyone is super worried this could be the end of him," the insider added.
