Spicy! Kourtney Kardashian & Scott Disick Are Reigniting Their Romance In The Bedroom — Find Out Why

A source told RadarOnline.com that even though the 32-year-old party-boy only left rehab last week, things are already heating up in the bedroom with his on-again-off-again girlfriend, 36.

“Kourtney and Scott are having nonstop sex and she says that it is through the roof,” the insider revealed.

“She says that sober sex with Scott is the best they have ever had. They are going at it like high-schoolers and it is making their feelings for each other so much stronger right now,” the tipster added.

Scott was apparently floored by Kourtney's hot revenge body, and "is giving her everything that she ever wanted from him.”
