The 35-year-old reality star has been linked to Lionel Richie's daughter, 19, since last year, and it is said the couple are "talking about moving in together permanently" as their relationship continues to heat up.

A source added to E! News: "Scott and Sofia are still going strong and have gotten more serious the past few months. They have definitely had their ups and downs, but lately everything has been really good between them."

While Sofia's famous dad previously admitted he was "scared to death" by news of their relationship, it appears now he could be warming to the idea.

Another insider told the publication: "Lionel Richie has finally warmed up and accepted the fact that Scott Disick is dating his daughter Sofia.

"Lionel had a hard time with the situation at first, and warned Sofia to end the relationship before she got in too deep with Scott, but he now has finally come full circle."

Indeed, it's said Scott - who has three children with ex Kourtney Kardashian - is now welcome at family dinners, and Sofia has been allowed to spend time with his kids Penelope, five, Mason, eight, and three-year-old Reign.

The first source added: "Kourtney has recently been more open about Sofia coming around the kids, and has also let [boyfriend] Younes [Bendjima] do the same.

"It's a mutual situation and everyone seems happy about it. Sofia doesn't try and act like a 'stepmom' and doesn't want to ever impose on Kourtney but she definitely takes the role most days."
