Just like all fathers, for Scott Disick, there's definitely nothing more worth spending time with than being around with his children.

On Tuesday, Scott Disick posted a photo of him with his oldest child Mason on his Instagram page. While it is not yet clear if the image was new or has only been re-posted, what's obvious was the kind of joy Mason has brought to Scott's face as shown on the father-and-son bonding photo.

In the image, Scott and Mason were sitting inside a private plane, with Scott Disick wearing a gray hoodie and Mason sporting a black hooded sweatshirt pulled tightly over his head.

He captioned it, "Boys trip #killingit"

Reports say that after spending a month in the Cliffside Malibu rehabilitation, Disick has reportedly checked out of the rehab center and is currently an outpatient as he continues to get his treatments done.

While the father of three has been recently reported to be out and about several times during his rehab stay, some sources insist that Disick is really serious and committed in taking his treatments.

"He wants to make it stick this time because he has come close to losing everything," a source said. Following his split with Kourtney Kardashian a couple of months ago, Scott has been too outspoken about how much he wants to get his family back.

As Scott remains committed to his treatments, adding that he's got the full support coming from the whole Kardashian clan. One source revealed that Kourtney seems to be really impressed with Scott's efforts.

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