Princess Anne's daughter Zara Tindall sparks speculation of leaving UK

Mike Tindall and his wife Zara Tindall have left fans guessing with their surprising appearance in the latest video.

Princess Anne's daughter and her son-in-law appeared on the promotional clip for musician Chilli Chilton's upcoming single "9,000 Miles", set for release on July 4.

Prince William and Harry's cousin and her husband's participation in the social media clip has been taken by royal watchers as a hint about the couple's potential relocation plans as the song explores the theme of loving someone who lives in Australia.

The couple's moves sparked speculation as their involvement in promoting a track specifically about the geographical divide between Britain and Australia has fuelled long-standing rumours about the couple's future plans.

In the video, Mike is seen shirtless with a glass of beer, lip-syncing to the lyrics: "Problem 1, 9,000 f****** miles."

Zara appears separately in the clip, energetically dancing with glitter on her face whilst mouthing the words: "Two, it's clearly more one-sided."

Actor Jamie Dornan also makes an unexpected appearance in the promotional video, which was reportedly filmed at a private party, reportedly held at the couple's home, Aston Farm.

Mike and Zarah last visited Australia in January, where they attended the Magic Millions racing event on the Gold Coast.

Zara's hubby is set to return to Melbourne in July to watch the British and Irish Lions compete against the Wallabies, though it remains unconfirmed whether Zara or their three children will accompany him.

The couple have frequently expressed their affection for Australia over the years, with both making regular visits to the country.

Speaking to Australian Women's Weekly in 2019, Zara revealed that relocating to Australia permanently could be on the cards.

"Probably not while I'm still competing. It would be a little bit hard commuting. But after that, yes, I think if an opportunity came up, we'd definitely think about it," she said.
