Kourtney was also seen at one point on the balcony wearing a leather cap, dark sunglasses, and a baggy white T-shirt.

Her former partner of nine years looked healthy and happy as he bonded with his children, although it was not the first time he's seen the youngsters since entering rehab.

Kris Jenner, 59, last brought the children to see their father on October 25, where the family were pictured having their photos taken on the balcony together, but she was not present this time.

No doubt the visit was just the lift Scott needed to help him get through his stay, as he works on his issues.

He has reportedly been in rehab for over two weeks after a wild summer bender which included being affectionate with his ex Chloe Bartoli, spending time with an 18-year-old model, and making club appearances in New York City and Miami.

This is his fourth time in rehab. He has previously gone to rehab in Costa Rica, Florida and Connecticut.

A source told Us Weekly of the family visit on Sunday: '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.'

'He’s making progress but wants to make sure and there was no harm in staying a bit longer so he decided to stay another week or two to be safe,' the insider added.

Kourtney 'has been adamant about not keeping their children away from their father,' a source told ET in September. 'Scott sees the kids whenever he wants to.'

However, he recently broke down on KUWTK when he said: 'It's been a really hard time, going from like, having all of you guys to having nobody.'

He then cried.

'You forget what happens when you're on a binge,' said Kourtney on camera.

'I f**ked up. I made the worst decision I've ever made in my life,' he said.
