Sofia Richie Splits with Scott Disick

Sofia Richie has decided to break up with Scott Disick.

The 19-year-old model has ended her relationship with the 35-year-old reality star after nearly a year of dating, People reports.

The split comes after Scott was spotted getting cozy with another woman at Kanye West‘s listening party earlier this week in Wyoming.

According to sources, Scott‘s “old issues” caused Sofia to end her relationship before adding, “When Scott drinks, he is a sloppy mess and fools around.”

Just last weekend, Scott and Sofia jetted off to St. Barth’s to celebrate his birthday with his three kids.

UPDATE: The couple is still together! Check out the new photos and Scott‘s statement.
