Bethenny Frankel, 53, shows off her killer body in a revealing two-piece as she hits back at critics who say she is  ‘too old to wear a bikini’

Bethenny Frankel appeared on Instagram on Thursday to share a new bikini-clad video with her 3.4 million followers.

The 53-year-old former reality television personality — who’s been enjoying a holiday in St. Tropez — showed off her fit frame in a tiny black and white bikini that bared her cleavage and abs.

‘Many of you say at a certain age you’re too old to wear a bikini. This was in my drawer and it has tags on it,’ Frankel announced as she turned to show her backside.

She, who recently modeled a lilac one-piece swimsuit, continued, ‘So the big question I have for you is: Am I popping tags or am I not popping tags?’

The star reiterated the question as she typed at the bottom of the clip in white font, ‘Am I popping or not?’

Bethenny’s post was recorded poolside on a wood deck during a sunny day.

Her lustrous raven locks were pulled into a bouncy ponytail as she stood barefoot next to the turquoise water.

She wrote in the caption, ‘Are we gonna pop some tags?⬇️⬇️⬇️ #swim #bathingsuit #onepiece #poolside #confidence #bkiniseason.’

One fan, seemingly impressed by her figure, asked: ‘How much do you workout?’

The mother-of-one, who shares 14-year-old daughter Bryn with ex-husband Jason Hoppy, simply replied, ‘beach walks.’

She also took to her Instagram Stories to share outtakes in a separate swimsuit as she walked along the shoreline.

The former Real Housewives of New York City star modeled a blue one-piece and a coordinating pale blue sun hat.

The fashionista added stylish blue-rimmed sunglasses and tiny hoop earrings during the solo beach trek.

Frankel’s grid post has so far collected nearly 30,000 likes.

It comes after she recently sparked romance with German artist Niclas Castello following a beach day they spent together in St. Tropez.

They were spotted lounging on adjacent chairs as she beamed ear-to-ear. 

Earlier this year Bethenny announced her split from real estate investor Paul Bernon, to whom she was engaged to be married.
