Sofia's Instagram is packed full of shots taken by Scott and it was previously revealed that the model is helping her partner to become "be a better person." 

Despite previous inhibitions - the model has got the approval of Scott's ex Kourtney Kardashian and the mother-of-three really "trusts" Sofia.

A source told People magazine: "Everyone really likes her. They think she's a great influence and Scott is so in love, so it's not a problem. 

"Sofia is helping Scott be a better, healthier person. Kourtney feels confident that Scott and Sofia take good care of the kids. Scott is a great dad when he has his life together. It helps that Kourtney now trusts Sofia. The kids are allowed to spend time with her. Sofia likes having them and helps Scott. So far, the kids are giving Kourtney good reports about Sofia."
