Shelley Sullivan has drawn fresh attention after appearing noticeably slimmer at her latest high-profile party.
The 53-year-old MCoBeauty founder has undergone a significant change in appearance in recent years. Her weight loss has become a talking point among Sydney’s social circles, particularly since her 2024 separation from former husband Anthony Sullivan.
On Saturday night, Sullivan’s slimmer figure and youthful-looking complexion were among the details guests noticed as she hosted an extravagant Pink Panther-themed celebration at her rented Potts Point mansion.
The event reignited speculation that the businesswoman may have undergone cosmetic treatment. Sullivan, however, has not publicly confirmed having a facelift or any other cosmetic procedure.
The star-studded gathering brought together prominent figures from Sydney’s affluent eastern suburbs, including Sullivan’s close friend and fashion designer Pip Edwards, who attended with her new boyfriend, Nicholas Nogarotto.
Edwards and Nogarotto arrived at the mansion holding hands. She wore an oversized white T-shirt with pink high-waisted trousers, while he opted for a dark button-down shirt and loose-fitting pants.

Columnist Melissa Hoyer made a statement in a dramatic black gown and aviator sunglasses, while artist Daimon Downey paired a white shirt and trousers with a pink T-shirt.
Throughout the evening, Sullivan was accompanied by her much younger new boyfriend, Justin Green.
The couple’s relationship became public earlier this year when Green joined Sullivan at her Valentine’s Day party at her Sydney home. He mingled with the celebrity guest list, which included Edwards and Downey.
Still, it was Sullivan’s own striking appearance that commanded attention at the weekend celebration.
The beauty entrepreneur – who last year sold her 50 per cent remaining stake in MCoBeauty to Dennis Bastas’ wellness conglomerate DBG Health after building it to a $1billion valuation in less than five years – showcased her dramatically slimmed-down figure in a shimmering, mermaid-inspired dress by Leslie Amon.
The gown, which featured starfish embroidery and a dangerously short hemline, is worth $500.
And the party itself was every bit as extravagant as guests have come to expect from Shelley.

There was also a man with dwarfism dressed as Inspector Jacques Clouseau, while a bubble machine, DJ decks and disco lights helped turn the mansion into a nightclub.
Waiters meandered through the crowd handing out pink shots as guests danced into the early hours.
Shelley appeared to be one of the party’s biggest revellers, with videos shared to her social media showing her dancing and grinding on the dance floor with Inspector Clouseau and others.
Curiously, several images from the evening posted online showed guests in fancy dress conspicuously dusted with white powder.
This must surely have been a tongue-in-cheek ode to the debauched parties of 1980s Hollywood and there is no suggestion that any illegal drugs were involved.

Shelley made her mark in the 1990s with her model and talent agency before launching her thriving ‘masstige’ beauty brand ModelCo in 2016.
Masstige is a retail term referring to a product that is marketed as ‘prestige’ or premium but is in fact mass-produced and inexpensive.
The beauty boss launched her brand’s Tan Airbrush In A Can more than 20 years ago and it still sells a bottle every 36 seconds worldwide.
She is also credited with introducing the world to the first heated eyelash curlers.
ModelCo has overtaken legacy beauty brands like L’Oréal, Maybelline and Rimmel in the Australian market.
The likes of Kendall Jenner, Hailey Baldwin, Rosie Huntington-Whiteley and Elyse Knowles have represented the internationally famous line.
In 2022, MCoBeauty was approached by a large Australian conglomerate which acquired a portion of the business.
