Who is Dennis D and What is he Doing With Bravo?

So I was perusing AVN.com, (here)(Adult Video News), to see if I could get any sales data for DANIELLE'S sex video, and I happened to notice this article;(copied from AVN)

DNA Owner Dennis D. Shooting Reality Show

Posted Aug 3rd, 2010 02:44 PM by Steve Javors

LOS ANGELES—DNA owner Dennis D. has always been a busy man. While DNA is still in business, though with a lower profile, he’s got mainstream projects firing on all cylinders.

D. told AVN today that he’s currently filming a reality TV show that’s slated to air on Bravo this fall that follows the exploits of him and two friends. The show is a spin-off of a popular show currently on the cable network. D. wouldn’t divulge the name of the show because it’s currently in production.

 OK. I'm intrigued. A "popular" BRAVO show, "currently on the network"...............SPIN-OFF???
Dennis has a TWITTER, so I'm off to TWITTER-STALK him a little, and see if I can find any more clues about this one.
(EDIT/UPDATE) OK-so He's following 21 people on TWITTER. Here are all of the women he is following, copied from his list. LIZZIE GRUBMAN is one name that stands-out for me as a "possible" here. Her name has been mentioned as a replacement for BETHENNY a few times.(copied list from TWITTER)
