Inside star-studded Moët & Chandon party on Sydney Harbour

The former foreign minister made a very public appearance with entrepreneur Luke Hepworth – further fuelling claims they’re an item.

A slew of Australian celebrities pulled on their best outfits to attend a glamorous party on Sydney Harbour on Thursday night.

Moët & Chandon kicked off its four-night “Effervescence” festival with a star-studded party at the brand’s specially installed pop-up bar at Mrs Macquarie’s Chair.

Former foreign minister Julie Bishop led arrivals on the black carpet, rocking a stunning sleeveless gown that showed off her toned arms.

The 66-year-old teamed her formal dress with a pair of open-toe shoes and a trendy box clutch, finishing the look with a pair of sparkly earrings.

Julie arrived with entrepreneur Luke Hepworth, 48, posing for snaps together and further fuelling rumours the pair are an item – despite the fact Luke has denied the claims.

P.E Nation founder Pip Edwards was also at the celebrity party, wearing a sheer black Mariam Seddiq gown that cut across the shoulder and gave a stunning silhouette.

The racy bodice dress also featured cut-outs across her midriff and put her legs on display while remaining modest thanks to the black mesh.

The 42-year-old teamed her stylish outfit with bold black make-up and oversized gold earrings, wearing her signature blonde locks with loose curls.

To finish her ensemble, Pip chose a pair of patent black open-toe heels and a small clutch.

Madeline Holtznagel, 26, attended with pub billionaire boyfriend Justin Hemmes, 49 – with the pair posing for an adorable couple photo at the start of the night.

The young model opted for a black silk clip dress with a revealing mesh panel across her midriff that flaunted her abs – while Justin wore a suit and bow tie.

Georgia Fowler turned heads at the event in a black jumpsuit with a sheer corset-style top that flaunted her midriff.

The 30-year-old New Zealand model wore her brunette locks in loose waves over her shoulders and chose a strappy pair of black heels to complete her outfit.

Today show’s Brooke Boney stunned in a neon yellow dress that she paired with black accessories – while model Montana Cox opted for a similar strapless dress but in black that she paired with pointed bow heels.

DJ Calvin Harris also surprised attendees with a live performance ahead of his headline performance at Festival X this weekend.

The final night of the Moët “Effervescence” experience has already sold out, but tickets are still available for Friday’s event and Saturday’s day party.
