Scott Disick's reps denied allegations that Kourtney Kardashian's long-time boyfriend's wild past included taping one-night stands with various vixens in the Hamptons, then robbing them blind, according to an old pal who spoke with Star Magazine.

"It's true that Scott began videotaping himself having sex with girls when he was in his late teens, and then he'd steal from them," said Disick's clearly-former friend and model Brittany Reichek.

Reichek claims Disick and his friends used to claim to be rich stockbrokers at Hamptons clubs to pick up girls. The would then take the unsuspecting lady friends back to their parents' house, which they claimed was theirs, and record an ensuing sexual tryst.

"When the time was right, Scott and his friend would go through their handbags and steal just about anything they could get their hands on," including cell phones, camera, cash and even credit cards, Reichek claimed, saying the reality star pulled off the scheme at least 50 times. "I think Scott got as good a high just from the actual things he stole."

Disick denied the allegations through a rep.

Reichek said she believes Disick has changed since his wilder teenage years, but his motivations are "only for self-preservation, not to be a better person."

The revelation, if true, comes at a particularly fraught time for Disick, as he and Kardashian have reportedly hit the rocks despite the recent birth of their second child, Penelope Scotland, according to Radar Online.
