Kourtney Kardashian is back together with the father of her three children.

Kourtney Kardashian is reportedly back with the father of her three children, Scott Disick, after one and half years apart.

Two sources confirmed the reunion with E! News, saying that the pair have been back in a relationship for a few months, but are not living together.

“They are back together and giving their relationship a try again,” one source said to the entertainment channel that hosts Keeping Up With The Kardashians.

The reason behind the rekindling of the relationship is said to be that Scott has “mellowed out a lot and hasn’t been partying”, according to the other source.

E! News also reports that the pair “both want to make it work” for the sake of their children Mason, 6, Penelope, 4, and 23-month-old Reign.

There had been signs that a reunion could be on the cards. For one, the 37-year-old fashion designer hadn’t ruled out getting back together with Disick, who she began dating in 2006 and split with in July 2015.

Earlier this year the she told the USA’s Today Show that she couldn’t predict what might happen down the track.

“We’re not getting back together right now, but I don’t know what the future holds in life, in God’s plan,” she told the show’s hosts.

“But we’re just doing our best to be the best parents. Like, he came with us to Vail and it was great. But, like, we’re friends at this point.”

In addition to their holiday to ski-spot Vail in Colorado, 33-year-old Disick also celebrated Thanksgiving with the entire Kardashian family last year.

And then just a few weeks ago the pair were spotted holidaying in Mexico.

And then there was the fact that they dressed up as a family of superheroes for Halloween.

Really, it’s a wonder they were able to keep the relationship a secret for so long.
