The 'Keeping Up With The Kardashians' beauty - who split from her partner earlier this year after nearly a decade together - is reportedly pleased her former flame is making good progress in rehab and focusing on their three children, Mason, five, Penelope, three and Reign, 10 months.

A source told PEOPLE magazine: "Scott is doing well and seems very happy. He is committed to staying sober. He is happy to get his life back in order and is focused on being the best dad for the kids.

"Kourtney is very pleased that Scott is doing so well. She is happy that he is finally focused on his sobriety. She likes that he is really making an effort when it comes to the kids. She is starting to trust him more, but there are no talks of getting back together yet."

Meanwhile, the 36-year-old television personality previously took her children to see their father in rehab where they enjoyed some birdwatching with the 32-year-old model.

An insider shared: "Scott was really happy to see the kids and was very loving with them. He visited with them inside for awhile and then took them outside to admire the view from the balcony.

"Kourtney stood back and let Scott do his thing with the kids. But she seemed to be on decent terms with Scott and they were chatting from time to time."
