Emma McKeon's ex Cody Simpson attends F1 party with mystery woman he keeps away from the cameras as A-listers descend on Marmont at Crown

Cody Simpson appeared to be enjoying the single life on Friday night as he attended a ritzy Formula One party in Melbourne with a glamorous mystery woman. 

The pop star, 29, who split from Emma McKeon in late 2025 after four years of dating, arrived with a stunning female friend he made sure to keep away from the cameras.

Daily Mail witnessed Cody place a friendly arm around the woman's waist as he ushered her inside Marmont at Crown, after posing for photos alone. 

Cody also declined to have his arrival with the blonde beauty filmed, despite footage being captured of other A-list attendees attending the glitzy event. 

Daily Mail has reached out to Cody for comment. 

The night out with his friend comes just weeks after news broke of his separation from competitive swimmer Emma. 

Cody's sister Alli confirmed the rumours on The Morning Show last month, saying her brother and the Olympic athlete had 'moved on' from one another.  

'She is like sunshine in human form, so I'm just so happy they can move forward,' Alli said.

While Alli did not share a reason for the split, she explained the pair, who began dating in April 2022, want privacy as they navigate the future.

'I don't want to speak for either of them, this is their private time and their business and I love them both dearly,' she said.

And it would seem Cody is in the throes of moving on from their relationship, as he has recently been making some new music and attending A-list events.

The Tequila Don Julio 1942 Pole Position party at Marmont on Friday night certainly provided plenty of fun to keep the singer and other notable guests occupied. 

The no expense spared soiree saw some of the most famous faces in Melbourne's social scene arrive at Crown Towers' golden carpet in statement supercars. 

Grammy nominated rapper Swae Lee took to the stage just after sundown, with the likes of Bec Judd, Lana Wilkinson, and Nadia Bartel dancing up a storm in the crowd. 

Jessie Roberts, Sarah Lucas and Jessie Murphy weren't far behind, while celebrity chefs Shannon Bennett and Curtis Stone were also spotted enjoying the atmosphere. 

Jules Neale also appeared to be making the best of single life following her split from husband Lachie, stepping out at The Crown with a close female friend. 

Later in the night, things kicked up a notch when Ty Dolla $ign took to the stage for the headlining act. 

Stella Klim was front and centre, sporting a massive grin as she filmed the award-winning performer singing to the crowd.

Booby Tape founders Bianca and Bridgett Roccisano, Mia Fevola, and Hannah Dal Sasso weren't far from the action either. 

Meanwhile, the likes of Pip Edwards, Tim Robards, Erika Jayne, Lindy Klim, Jade Kisnorbo, Maria Thattil, and Brooke Blurton seemed content to mingle in the crowd.
