Kourtney Kardashian and Scott Disick are back together - report

Kourtney Kardashian has reportedly reunited with Scott Disick.

The 37-year-old reality TV star split from Scott last summer (15), but the pair have stayed close as they co-parent their children, son Mason, six, daughter Penelope, four and 23-month-old Reign.

However, E! Online is now reporting that the duo have been back in a relationship for a few months, though they're not living together. The news comes just a few weeks after reports that Kourtney and the businessman were seen getting cozy on a family holiday to Mexico.

"They are back together and giving their relationship a try again," a source close to the couple tells E! News.

Kourtney is reportedly impressed by the fact that Scott has quit partying, and has "mellowed out".

The pair were together for nine years and have remained amicable since their split in July 2015, with Scott still joining The Keeping Up With The Kardashians star on family trips and for the holidays.

While Kourtney shared on an episode of her TV show that she didn't want to give Scott false hope of a reunion, she admitted in a television interview earlier this year (16) that she wouldn't rule out them getting back together either.

The brunette beauty was quizzed about her relationship status during an appearance on breakfast show Today in April (16), when co-presenter and family friend Kathie Lee Gifford asked, "Are you and Scott getting back together, or will you ever get married?"

"I don't know," she laughed. "We're not getting back together right now, but I don't know what the future holds in life, in God's plan. But we're just doing our best to be the best parents."
