It seems that Scott is officially "on" with Justin Bieber's ex-girlfriend, Sofia Richie. The cute, blonde model is the famed daughter of Lionel Richie, and sister of designer, Nicole Richie. She spends her days jetting around the world for appearances, shoots and apparently quality-time with one Scott Disick. via @sofiarichie A source from People claims, "Sofia seems smitten. She constantly giggles around him. They are very flirty. Scott takes care of her, opens the car door and pays for everything." Though Sofia claimed that the two are "just homies" back in May after Disick's infamous Cannes women-binge, but it looks like the two are definitely an item as of recent. It's Scott's weekend with Sofia Richie. Lionel Richie gets her every other weekend. It's called co-parenting.A post shared by North West (@norisblackbook) on Sep 21, 2017 at 9:03pm PDT The two have been spotted anywhere from New York to L.A. to now, Miami. The two were caught strolling, kissing and lounging on a Miami beach despite their 15-year age gap. Disick, who once dated with Sofia's stylist and friend Chloe Bartoli, has apparently driven a wedge between the two women. Reports claims they are 'no longer friendly' thanks to Disick and Richie's coupling. via @chloebartoli It's half your age plus seven, Scott. This is a new level of gross for you. Source: TMZ
