The 34-year-old Keeping Up With the Kardashians star and Kourtney Kardashian's ex and Lionel Richie's 19-year-old daughter, a model, had sparked romance rumors in May when they got flirty on a yacht around Cannes, days after he was spotted getting cozy with a few other women. Sofia later tweeted she and Scott are "just homies."
In June, they were spotted FaceTiming each other. In September, they spent time together in Santa Barbara and were also seen kissing on a trip to Miami, where they went out to dinner and received a cake with the inscription "Congratulations Scott & Sophia." No explanation was given. That month, E! News learned the two were hooking up but were not exclusive.
"From Scott's side, it's not serious. From Sofia's side it is," a source close to Sofia told E! News exclusively on Friday.
