Things are getting serious between Scott Disick and Sofia Richie (and fast). The couple was recently spotted on an Italian vacation — and it looks like they are ready to take their May-December romance to the next level.

Sources are revealing exclusively to LIfe & Style that while Sofia, 19, ignored engagement questions recently, she is already talking marriage with Scott, 34. “Scott “would spend 24 hours a day with Sofia if he could,” an insider says before adding that the pair has already gone ring shopping.

That is not good news for Sofia’s dad Lionel Richie, who admitted he is still scared to death about his daughter’s relationship with the controversial reality star. “I’m scared to death about anybody dating anybody,” he told LIfe & Style. “She’s going to go take the turn and get through it and come out the other side…. It will course itself.” Scott Disick’s ex, and mother of his three kids, Kourtney Kardashian, is also not a fan of the couple and refuses to let her meet Mason, 7, Penelope, 5, and Reign, 2.

Kourtney “thinks Sofia is too young to be a good role model,” a source told In Touch. “She insists that Scott has to be in a serious relationship for at least six months before introducing a girlfriend to the children.” However, Scott just thinks Kourt is upset she has been “replaced” with a younger, hotter model.

“He’s convinced Kourtney is jealous that she’s been replaced by a hot, younger model, who also comes from a famous family,” the source added. “Kourtney also secretly feels betrayed by Sofia, as she’s known the Kardashians for years and yet still pursued Scott. Kourt feels like Sofia has stabbed her in the back.”
