The "Real Housewives of Atlanta" star stopped by "Watch What Happens Live" on Sunday, where she addressed rumors that her breasts aren't the only part of her body she's had work on.
"You know that now the big thing is wondering if you had your butt done," host Andy Cohen said to Williams.
"I know! I heard Kandi [Burruss] came on the show and you asked her and she said she thinks ... she knows this is cornbread fed," Porsha said before standing up to give the audience a view of her backside.
"Honey, don't try me boo boo," she added, while shaking her booty for the camera. "This is 100%!" she confessed.
The reality TV star likewise opened up about her decision to get her breasts done in 2014 while chatting with Us Weekly.
"[My chest] was something I always wanted to fix," she said during the interview. "The day I brushed my teeth and they jiggled, I screamed with joy!"
"I have always loved my body," she said in another interview with OK!. "I'm a woman with curves and hips that don't lie! So what's wrong with a little more of me to love? I finally got my twins."
