Sofia Richie is "helping" Scott Disick "be a better person" and Scott's ex Kourtney Kardashian really "trusts" the model.

The 20-year-old 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."

Meanwhile, a source previously claimed Sofia is "fed up" with Scott.

The insider said: "Sofia broke up with Scott after the pictures and rumours of his behaviour in Wyoming were floating around. 

She couldn't take it anymore. Scott has been off the rails recently and is not in a good place. He goes in waves of partying really hard and then will have his good days and it's just very toxic behaviour. 

It's very up and down. Sofia was fed up and heavily influenced by friends and family, especially Lionel, to break it off. Lionel has warned Sofia to get out while she can and move on. She couldn't stand for being cheated on and being in such a toxic relationship."
