The Game of Thrones actress, 27, and American singer, 34, confirmed their split last week amid rumours they were living separately.
The British star has kept a low profile since the news broke, but she has now been pictured in Spain as she filmed her new ITVX drama, Joan, which revolves around the story of Joan Hannington, a mastermind of several jewel heists in the 1980s.
Turner was seen sporting a blonde cropped wig and a large temporary back tattoo as she had a cigarette during a break from production.
The actress was spotted wearing a black vest, grey shorts and navy Adidas sliders in the photos obtained by multiple outlets as she held her iPhone, which had a Toy Story phone cover.
The Pixar franchise holds significance for the former couple, who got matching tattoos with words from the film in 2018. Jonas’ reads: “To infinity”, while Turner’s completes the line with: “& beyond.”
Following days of speculation, Jonas filed for divorce from Turner on September 5 in Miami Dade County, Florida, stating that their marriage was “irretrievably broken”.
Amid reports that their marriage had collapsed over their different lifestyles, the former couple issued a joint statement, clarifying that their decision to divorce “after four wonderful years” had been mutual.
Over the weekend, the Sucker singer admitted “it’s been a tough week” during his Jonas Brothers concert in Los Angeles. It followed backlash he’s received on social media since their divorce was confirmed.
Amid his show at the Dodger Stadium on Saturday, he told the crowd: “It’s been a tough week. I just wanna say, look, if you don’t hear it from these lips, don’t believe it. Okay?
“Thank you everyone for your love and support. Me and my family love you guys.”
The two had a prenuptial agreement that Jonas expects will be enforced, according to the filing.
Previously, the family had been based in Florida, with the children spending the last few months with Jonas on tour, accompanied by family, while Turner worked in the UK on the ITVX drama series.
