‘It was legendary,’ Butler told ET. ‘It was amazing. I loved getting to see that. What an exciting cover. I loved it.’

The pair first sparked romance rumors in December 2021, before going public with their relationship in March 2022.

Austin also spoke about his new film, explaining: ‘I was a fan of the book from the time I was 15. I was an enormous fan of the first film, so I feel very fortunate to be a part of this. It’s really exciting.’

Butler is a newcomer and will play Feyd-Rautha Harkonnen, Baron Harkonnen’s young nephew, and planned successor as ruler of Arrakis.

He stars alongside A-listers including Zendaya, Timothée Chalamet and Florence Pugh, in the project.

‘It’s such a fun group of people in general that we have a lot of fun together. They’re inspiring to me in many ways, so we all have fun together.’

Zendaya, 27, arrived to the bash in a slinky black dress, and her tresses slicked down in a wet look.
