As PEOPLE exclusively reported in June, a source close to the musician said that “Joe is taking the relationship very seriously” and Sophie is “different from the other girls he has dated.”

The couple have kept fairly tight-lipped about their romance.“I’m in a relationship, but it’s a very private relationship,” Turner told the U.K.’s Sunday Times in July. 

“I very much isolated myself for a while and forgot what was fun. Going out with friends, going out to eat, not really having a care,” she told the publication. “And people I’ve met recently in my life have drawn me out of that.”

She continued, “It really helps you own those insecurities. The things I tortured myself about before, I can forget about.”

According to the British starlet, she’s in a much more positive place in life than she was before.

“I’m happier than I’ve been in a very long time,” she said.

Turner also opened up to InStyle this past spring about her high-profile relationship. “I found it easier to date someone who understands the industry or is in that world,” she said.

“You realize that you’re not going to see each other all the time,” she said, and added, “And you don’t feel like a jerk when you’re like, ‘My publicist says I can’t do this…’”
