Now that's a revenge body! 53-year-old Shannon Beador just announced she was divorcing husband David Beador on Oct. 27, and she's already looking so much trimmer. She took to Instagram on Oct. 29 to post behind-the-scenes pics of the Real Housewives of Orange County reunion, and we can't believe her banging bod!

"Reunion Season 12," she began in the caption of a photo posing with her hair stylist and makeup artist. "Big hugs to @erickabrannon and @prive_shay for continual touch ups on a very emotional day. ? And a huge thank you to my cast mates and fans who are lifting me up with their love and support! ❤️❤️❤️" Shannon wore a curve-hugging little black dress that showed off her amazing cleavage and legs, and fans definitely took notice. "You look amazingly healthy and happy!" wrote one supportive fan, while another excitedly exclaimed "look how small she got!" "Wowser, look at you! You go girl!" agreed another, along with about a million "you look amazing!" comments.

Shannon first gained weight after her fight with Vicki Gunvalson.

Shannon was never overweight, but she admitted exclusively to Life & Style that she “put on 40 pounds in eight months" after she ended her friendship with Vicki Gunvalson. Now, she definitely looks noticeably slimmer — and happier! Fans are dying to know how she lost weight, so we did some digging.

She's supplementing her diet with 310 Shakes.

On Oct. 30, Shannon revealed that she uses 310 Shakes as a "plant based and gluten, dairy, and soy free" option when she "doesn't have time to sit down for a meal." But of course there's more to it than that! It appears that Shannon has been buckling down with her diet and exercise for months now.

She's getting plenty of exercise and working with a nutritionist.

"Sweating my a– off walking up this hill! ? #stilldespiseexercise #tryingmybest," she captioned a sweaty photo on Oct. 14. Months earlier on June 13, Shannon started working with nutritionist-to-the-stars and trainer Dr. Tim Ramierz, squeezing her arm fat and saying "this will become muscle soon! ?? #workingonit #willgetthere." Clearly she stuck with the plan, because she showed off progress on Aug. 2 saying that she was doing 30 minutes per day of exercise. Clearly the hard work paid off because she looks better than ever!
