From www.tmz.com- Dr. Drew Pinsky’s former patient — a term we use very loosely — Mary Carey is striking back at him the best way she knows how — by releasing a new porno that mocks the doc and his “Celebrity Rehab” reality show.

The porno is aptly titled “Celebrity Pornhab with Dr. Screw,” and in our behind-the-scenes footage, you’ll see there’s not much difference between the satirical XXX flick and the actual TV show — except for the gratuitous sex, of course.

By the way, this is Carey’s comeback to adult films. Dr. Drew frequently urged her to retire from skin flicks as part of her rehab. Guess she’s skipping that step.

UPDATE: The real Dr. Drew just twittered about “Pornhab,” saying, “For those of you wondering about my feelings about Mary Ellen Cook’s [Mary Carey’s] choice to mock : Res ipsa loquitur. Makes me very sad.”
