"Soooo you guys finally talked me into trying a waist trainer! I can't believe how tiny it makes my waist I'm obsessed with @nowaistclique waist trainer and it doesn't show through my clothes," the former "Housewife" captioned the snap.
In the photo, the mom-of-six flaunts a whole lot of cleavage while her waist looks seriously unreal. The reality star got a tummy tuck last year and hasn't been shy about showing off her new body!
