Before settling down with Game of Thrones actress Sophie Turner, the singer dated multiple pop stars in Hollywood. Joe famously dated Taylor Swift, who is known for writing hit songs about the men she has dated. Though she doesn’t confirm exactly who the song is about, fans have suspected that “Forever & Always” was written after the two broke up.

Demi Lovato confirmed that her song “Gonna Get Caught” was written about Joe. The singer, who appeared on Camp Rock alongside the boybander, admitted during a 2016 interview with Stephen Colbert that she was “a little burned at the tender age of 15.”

When asked by the late show host who broke her heart, she replied, “[Nick’s] brother Joe.” 

Adding, “I was writing my first album and writing a song called ‘Gonna Get Caught,’ and [Nick] was in the room. We were all writing together, and he was like maybe it has a happy ending, ya know? I was like no! I think he gets caught and everybody sees he’s a heartbreaker and Nick’s like, ‘Why don’t we just write the chorus.’ It was like going back and forth, it was so funny. Poor thing, he’s been stuck in the middle for a while.”
