Looks like Scott Disick is finally getting the last laugh.

“[Scott] is getting up to do a completely takedown of the Kardashians,” an insider tells In Touch exclusively. “He’s been compiling a 10-year dossier on the family. It includes the dirty tactics Kourtney, Kim, Khloé, and mom Kris Jenner use against their enemies, how scripted the drama on Keeping Up With the Kardashians really is, and the women’s innermost secrets.”

And he has some major tea to spill; he was there when Lamar Odom nearly lost his life to an overdose and saw how everyone — including Kim — reacted to Kanye West’s mental breakdown that landed him in the hospital late last year. He’s even going after his baby mama, Kourtney Kardashian, saying she was “begging” for a reconciliation before she started parading around her new, much younger boyfriend.

Now that he knows he wants to tell his story, he just needs to figure out how he’s going to do it.

“Scott is fielding offers from production companies for his own docuseries that would focus on his many issues with the family,” the insider says, noting that he’s signed previous non-disclosure agreements. A second source says he won’t let that stop him, “He’s already running his mouth to all of his hookups, telling them the family’s secrets. He knows everything, and he’s telling all.”
