Kourtney Kardashian and Scott Disick seem to be in a good place after having been broken up for well over a year.

A source close to the reality stars -- who are parents to Mason, 6, Penelope, 4, and Reign, 1 -- tells ET that Scott "has been consistently on his best behavior for the past two months" to the delight of Kourtney. "He’s not been partying or drinking," the source says. "This is the first time we’ve seen Scott be this good in a very long time. Yes, that is always something Kourtney wanted for Scott -- to calm down and be at home."

While the two are quite amicable, reports that they are back together are "completely untrue," according to the source, who insists that "nothing between Kourtney and Scott has changed."

"She is not going to forget years of tears and heartbreak because he is on a six-week streak," the source continues. "They are not back together.”

A recent Snapchat photo posted by Kourtney seems to corroborate that she has not rekindled her relationship with Scott. Last Thursday, she shared an image of a gingerbread house that was gifted to her from mom Kris Jenner that included the names of her family members. Scott's name was noticeably absent.

This is not the first time a source for ET has debunked reports that the parents are getting back together. "Scott obviously wants to rebuild his family," a source close to Kourtney and Scott told ET last month. "He's in a great place, a much better place than he's been in in a long time. He hasn't been going out partying and has really calmed down on that front. He hasn't been traveling without the family or hitting the club scene. He's trying his very best to get his family back."

The source added that their relationship is “platonic and loving," though a recent photo posted by Scott of Kourtney during a family vacation to Mexico appears to be a bit flirtatious. Check it out:
