Real Housewives of Melbourne stars are used to turning heads as they arrive at events.

But on Sunday, Pettifleur Berenger was almost unrecognisable as she arrived at Cats The Musical premiere at the Regent Theatre in Melbourne.

The 51-year-old reality TV personality and local identity had her bronde locks pulled back into a high ponytail and back off her face, accentuating her taut forehead.

Pettifleur's fully-lined eyes looked intense with the jet black eyeliner, while her pearlescent bronzer highlighted her high and particularly rounded cheekbones.

Meanwhile the socialite's whitened teeth coupled with her light lipstick and darker lipliner look, made the starlet's lips appear puffy.

Wearing a sleeveless black dress flowing down just past the knee with a high neck and pin-tuck waist detail, the reality TV star cut a sleek figure.

The ensemble was paired with black and gold platform pumps, with a red Saint Laurent leather clutch adding a bright pop of colour to the ensemble.

Ladies night out: Pettifleur enjoyed the musical with her co-star Gamble Breaux

Her particularly taut-faced look is very different to a flashback shot of the Switch the B**** author, which she posted to Instagram earlier this year.

The photo from almost 20 years ago, shows the then 32-year-old in a slinky black dress standing in-front of a Christmas tree with a very serious look on her face.

Even then the Sri Lankan-born beauty sported large luscious lips, done up in a red hue.

However on Sunday, the reality TV star seemed to be turning back the clock, looking even younger than she did in the 1997 shot.

Recent change? The 51-year-old starlet tells fans on her website that she's never had any Botox or fillers at the age of 50, however her new look suggests she may have changed her mind on the procedures

According to Pettifleur's website, unlike some of her co-stars, she has not had any work done, telling fans: 'She can proudly say, at 50 years of age, she hasn't had any Botox or fillers!'

'She attributes this to well-mixed genes and clean living,' it adds.

The property developer first joined the cast of The Real Housewives of Melbourne in Season 2, at the same time Gamble Breaux joined the series, after Andrea Moss left the hit Foxtel show.

Making her debut on screens in 2014, the popular personality was described as 'Determined, feisty and glamorous'.

Ruffling feathers: The property developer ruffled feathers among the cast, especially with Gina Liano and Jackie Gillies (pictured)

'Pettifleur thrives on a life of accomplishment and luxury. She is a successful property developer, lives in a penthouse in the heart of the city and is mother to three fantastic boys,' her bio detailed.

The beauty was quick to ruffle feathers among the other housewives, especially Gina Liano, after a number of fights across the season.

However, for any fans worried she wouldn't return for another season, Pettifleur recently confirmed her part in Season 3 of the show, which is currently being filmed.

The 51-year-old posted a shot of herself being made up for the promotional shoot for the upcoming season, again displaying an almost unrecognisable look under layers of make-up.
