Luann de Lesseps, 58, Stuns in a Blue Bikini While Dancing on a Mexican Beach Amid Drama with Bethenny Frankel

Luann de Lesseps got her groove on while on vacation in Tulum, Mexico. 

The Real Housewives of New York City alum, 58, looked very fit and slim in the tiny blue bikini. 

She captured a short video of her dance routine, which looks just like how Real Housewives of Beverly Hills alum Lisa Rinna, 60, danced in the video for Luann's single Feelin' Jovani.

The reality TV personality has been sharing plenty of photos from her Mexican vacation.

In every one she wears a different bikini and hat. 

Earlier this month, the Countess once again criticized her former co-star Bethenny Frankel, 53.

'Now back to Bethenny. You know, listen, why bite the hand that feeds you?' she said during her December 23rd cabaret show at 54 Below in New York City – according to Page Six.

'Why bite [executive producer] Andy [Cohen]? Why bite NBC? You know, just go off into the sunset. You make millions and gazillions of dollars. If you claim you do, then why are you still harping on us? Why are you talking about us?'

Luann (born LuAnn Nadeau) got the crowd on their feet cheering when she quoted the Skinnygirl CEO's popular phrase: 'Leave us alone! Go to bed! Go to bed! Go to bed!'

De Lesseps used to be close with Bethenny but, in an October Instagram post, Frankel said she used to 'adore' her cast mates until she began to 'strongly dislike many of them.'

Have they changed? Or is it the toxic environment designed for ratings?' the Manhattan socialite - who boasts 7.6M social media followers - wrote.

'Am I biting the hand that fed me? Perhaps but maybe that hand deserves to be bitten. We have fed the machine ratings, ad dollars, catch phrases, and content. We get filthy and they get filthy rich.' 

She captured a short video of her dance routine, which looks just like how Real Housewives of Beverly Hills alum Lisa Rinna, 60, danced in the video for Luann's single Feelin' Jovani

She captioned the post: '#FeelinJovanihere in Tulum! Getting ready to head back to the #CountessCabaret before we kick off the #MarryFK tour! Which city are you coming to? See you there'

Luann wore a white straw hat with a black band as the video was filmed. She danced along a deck before it panned out to the beach and the sea beyond as her song played

Previously, Luann was married to French Count, Alexandre de Lesseps, from 1993 until their divorce in 2009

Previously, Luann was married to French Count, Alexandre de Lesseps, from 1993 until their divorce in 2009.

The former couple share two children together — 27-year-old son Noel and 29-year-old daughter Victoria.

She later tied the knot for the second time with Tom D'Agostino Jr. in 2016, but they divorced the following year in 2017.

'I'm a hopeless romantic. I'm not afraid to love. And I married and I don't regret anything,' the singer told Us Weekly in 2018 when opening up about the one-year marriage.
