However, suspicions of a relationship started in August 2020 when she told the Daily Telegraph she got "stuck" away from home during the pandemic and was residing in Australia.

"I didn't really want to go back to New York in the middle of a pandemic when it was pretty gnarly to say the least," she said at the time.

"I couldn't go home initially, and now that I can, I don't really fancy going back," she continued. "I have my own mother saying, 'Don't come home,' my 86-year-old mum. We are in a very challenging time!"
