Sicko! Scott Disick Caught On Camera Partying With Half-Naked, Drugged-Up Teen Girls -- Kourtney Kardashian Disgusted

Just how depraved has Scott Disick's dark life of drugs, alcohol, and womanizing become? A disturbing new video has surfaced the shows Kourtney Kardashian's ex partying at a cocaine- and booze-fueled party with half-dressed teen girls -- and RadarOnline.com has the clip!

As RadarOnline.com reported, Disick recently resurfaced at a wild house party in Boca Raton, Florida, after Kardashian threw him out of his Calabasas, Calif. home. Shocking photos from the night showed him passed out next to a plate covered in a white powder, and one insider told RadarOnline.com, "People were drinking and doing cocaine."

Now, the new video shows just how twisted the party turned:

In the clip, obtained by RadarOnline.com, an unidentified teen girl wearing next to nothing is seen gyrating her hips with a hula hoop on top of a table as Disick arranges something on the table in the background.

A male friend can be seen videotaping the scene.

According to an insider, the girls Disick, 32, partied with that night ranged in age from 16 to 18, and the home belonged to one of their parents.

But the party didn't end there: The insider said that Disick continued the night with several of the girls in his suite at the Boca Beach Club Resort.

As RadarOnline.com has reported, Disick's behavior in recent weeks has so disturbed his ex Kardashian that she has seen a lawyer about angling for primary custody and plans to ask Disick to bring a chaperone to his visits with their children.

After not seeing Mason, 5, Penelope, 3, and Reign, 6 months, for more than three weeks, Disick returned to L.A. by July 16 and reunited with the children during a visit.
