Beauty industry trailblazer Shelley Sullivan debuted her shock weight loss at the prestigious Silver Party in Sydney on Saturday night.
The MCOBeauty founder, 51, appears to have slimmed down since her sudden split from her husband Anthony following an explosive argument in May last year.
An emotional Shelley was spotted being consoled by her mother just a few weeks after their break-up, and it seems the entrepreneur has now undergone a makeover.
Shelley was all smiles as she flaunted her new figure in a sizzling red dress at the annual charity event, which was held at Justin Hemmes’ Vaucluse mansion.
The businesswoman stood out from the crowd in the bright frock which had an off-the-shoulder neckline and daring thigh split.
Sweeping her short blonde tresses back from her face, Shelley opted for a minimal makeup look as she posed with fashion designer Jonathan Ward and other friends.

The Silver Party, held annually by the Sydney Children’s Hospitals Foundation, is one of the city’s most prestigious charity galas.
Held this year at a lavish harbourside home, the event drew hundreds of Sydney’s most influential business leaders, philanthropists, media figures, and celebrities.
Shelley’s slimmed-down appearance at the event comes after her abrupt split from husband Anthony following seven years of marriage.
An acrimonious fight reportedly prompted Anthony to leave the country and head to the US, while his wife moved into the five-star InterContinental Hotel in Double Bay.
The devastated mother-of-two was later seen being comforted by her mum Kerrie in Sydney’s financial district, where her multimillion-dollar business is based.
The pair looked visibly distressed as they shared a tender moment amid her marital breakdown.
At the time, Shelley told Daily Mail Australia she would not be commenting on the marriage break-up.
‘Shelley is absolutely shattered by the split,’ a close friend previously told Daily Mail Australia.

‘Anthony was her rock, she’s devastated – her marriage was everything to her.’
The businesswoman’s close-knit group of friends are doing their best to support her as she deals with the split.
‘She has an amazing network that has just put their arms around her at this time,’ the friend added.
Anthony is an accountant and CEO of Quantaco, which provides financial services to companies in the hospitality trade.
The couple had known each other for years and were friends before starting to date, and then tied the knot in a lavish ceremony in Point Piper in 2016.
The pair have since moved out of their $11,000-a-week heritage-listed rental mansion Leura in Bellevue Hill.
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.
