'Mob Wives' Star Renee Graziano -- My Gruesome Ass Renovation

"Mob Wives" star Renee Graziano got worked over HARD by a plastic surgeon -- while wide awake -- all in the pursuit of the perfect butt, and the video is a total train wreck ... centered on the caboose, of course.

Graziano tells TMZ she sought out fat-sucking lipo doc Ayman Shahine to harvest gobs of fat from her butt and lower back to re-shape her ass. As we told you ... GG from "Shahs of Sunset" also got a butt lift recently.

According to Doc Shahine, Renee's fat transfer took under 2 hours ... and he recorded it for a possible reality TV show.

Two highlights: Renee's groggy testimonial -- and the giant Italian moon that's about to hit your eye like a big pizza pie.
