Kourtney Kardashian is slowly but surely moving on.
The 36-year-old reality star split with her longtime love, Scott Disick, over the Fourth of July weekend, and is holding strong two months later. One clear sign the two aren't getting back together anytime soon? Scott is now treated as a regular "guest" at the Calabasas, California home he once shared with Kourtney and their three children -- 5-year-old Mason, 3-year-old Penelope and 8-month-old Reign -- meaning he can no longer come and go through security as he pleases.
Scott was spotted visiting the family residence on Sunday, but had to wait in the visitors line, as opposed to being on the residents list. A source tells ET he had to wait 10 minutes before he was eventually allowed through.

Prior to his visit, the 32-year-old Keeping Up With the Kardashians star was seen picking up some goods at Gelson's super market in Woodland Hills, California. He moved out of Kourtney's Calabasas residence in July.
Another source close to the former couple tells ET that the chances of Kourtney taking Scott back are slim to none.
“Kourtney is not taking Scott back -- never, as of right now," the source says. "Kourtney has been through a lot of drama with Scott over the years but it's for real this time."
Still, despite the status of their relationship, Kourtney has also been adamant about not keeping their children away from their father. "Scott sees the kids whenever he wants to," the source says. "Despite all of Scott's addiction problems, he is a great dad and loves those kids with all his heart, and they are obsessed with him. He comes to her house to see them."
"Kourtney and Scott only text and talk when it's about the kids," the source adds. "She still refuses to talk to him about anything else.”
Instead, Kourtney has seemed to channel a lot of her energy into working hard at the gym post-split. The mother-of-three hasn't been shy about showing off her bikini body lately, and looked incredible on Monday enjoying a frozen treat in Malibu, California with Mason and Penelope. Wearing a tight white bodysuit and high-waist jean shorts, Kourtney is obviously in better shape than ever.
