Singer Rita Ora has fans wondering if she's about to make her Thor debut.
And a photo with the film's director Taika Waititi also sparked rumours there might be a romance between the pair.
The Voice judge, 30, shared the photo of the 45-year-old Kiwi director with his arms around her as they wore matching Gucci outfits.
While Waititi's face was partially covered by a cap, he was tagged in the photo captioned, "Good times, memories, random things on my phone and the ones I love".
The rumoured new couple were recently seen leaving a private jet alongside Chris Hemsworth, Elsa Pataky and Matt Damon in Sydney after returning from the Gold Coast.
