The former Bravo star, who switched to WE tv this year, announced that she's "been off the bad stuff for over two months" in the caption accompanying the sexy shot.

"#nosugar is working," she wrote.

"Cut out all processed food," she continued. "No fruit no artificial sweetener went full on @sweetleafstevia."

As she says, clearly her strict diet has been working for the 55-year-old television personality. She looks noticeably skinnier and more confident than she's been in years.
