Patrick Brammall has revealed why Sydney Sweeney's cameo in The Devil Wears Prada 2 was cut from the final film.

The Australian actor, who co-stars with Anne Hathaway in the newly released movie, revealed that the Euphoria star's role in the movie was removed for several different constraints.

'When putting a film together, things have got to go... and so Sydney Sweeney went! I never met her, but she was apparently in the opening sequence,' Brammall told the No Filter podcast.

He added that the Washington-born actress's role was omitted to improve the overall narrative flow of the film. 

'It is all for creative reasons and time, that sort of stuff. There were a few scenes that I shot that weren't in the movie,' he said.

Last week, it was reported that Sydney had filmed a small role in the long-awaited sequel to the 2006 hit movie, and that it had been removed from the final product. 

The actress, 28, had been due to feature in a three-minute scene where she was styled by Emily Blunt's character, yet it was scrapped because 'it did not work structurally.'

Originally, the scene had featured Andy Sachs (Anne Hathaway) reuniting with her former Runway colleagues, Miranda Priestly (Meryl Streep) and Nigel Kipling (Stanley Tucci), to save the fashion magazine from imploding amid a scandal.

In a bid for help, they enlisted the help of former Runway assistant Emily who now works at Dior, walking in on her while she was styling Sydney.

That scene no longer makes the final cut but it's been claimed that 'the team working on the movie were grateful for her participation, making the decision to remove the bit a difficult one.'

Sydney also did not attend the film's premiere last month.

Fans first learnt of her involvement with the movie when she was spotted arriving on the New York City set in August.

It comes after the actress touched down in Australia on Saturday to film a new Netflix series, and it appears she is already making friends with some of the eastern suburbs socialite set. 

The Euphoria star was seen living it up in a private box at the Sydney Swans vs Melbourne Demons game on Sunday at the SCG with Aussie heir Michael Porter, whose family owns Australia's leading condom business, Four Seasons.

The pair were seen cheerfully posing together as they watched the match and sipped on wine. 

Sydney got into the spirit of the game, styling a Sydney Swans baseball cap with a long-sleeve white T-shirt and slick aviator sunglasses.

The blonde beauty, who attended with her father Steven, was given her own team jersey, with 'Sweeney' and the number 21 emblazoned on the back. 

The sighting marked her first public appearance since confirming her romance with music mogul Scooter Braun – and it comes hot on the heels of their headline-making weekend at the Stagecoach Music Festival.
