The 34-year-old reality star and the 19-year-old daughter of music legend Lionel Richie confirmed their relationship in September after first being spotted together in Cannes in May, and sources now say that their relationship is continuing to go from strength to strength, though it is unclear how "serious" they are.

A source said: "[Scott and Sofia] are still going strong [and] having a great time. [They are] happy and having fun for now."

And insiders also claim there is no tension between Scott and his former on/off girlfriend Kourtney Kardashian - with whom he has Mason, seven, Penelope, five, and Reign, two - as the 'Keeping Up with the Kardashians' star "does not care" who he dates.

The source added to 'Entertainment Tonight': "At this point Kourtney isn't interested in Scott as a romantic partner. All that matters to her is that he is a good father to their children. He loves his kids and he's good to them. She does not care who he dates or who he spends his time with."

Whilst Scott might not have to worry about Kourtney judging his new romance, he is yet to win over Sofia's dad and 'Hello' hitmaker Lionel, who is "scared to death" about his daughter's new relationship.

He said: "Have I been in shock?! I'm the dad, come on. I'm scared to death, are you kidding me?"

Lionel is also said to be concerned that Scott's "playboy ways" could pose heartbreak for his daughter in the future.

A source said previously: "He thinks Scott is the worst person she could ever see and that he raised her better than that. He thinks she should have more respect for herself as a young woman. Lionel knows Scott's playboy ways and he doesn't want to see his daughter get hurt."
