Kourtney Kardashian isn't quite finished with her ex/baby daddy Scott Disick.

A source exclusively revealed to In Touch the duo has been hooking up over the past month, despite having split July 2015.

"They've been sleeping together for the last month on-and-off," the source said. "Both agree the sex is better than ever. Scott's been staying over at Kourt's and sneaking out early in the morning."

Further, while few people know of their secret hookups, the couple isn't doing a great job at keeping their business private, with the source adding, "They claim they want to keep this a secret for as long as they can, but they're being so careless that it's only a matter of time before everyone finds out."

Kourt and Scott, who are parents to Mason, 6, Penelope, 4, and Reign, 1, split last year after photos surfaced of the businessman cuddled up with an ex-girlfriend. Kourtney recently opened up about possible plans to marry her former beau, but insists she's in no rush to walk down the aisle.
