Joe Jonas’ was nervous about saying sorry to his former loves on his solo album.

The singer’s debut solo record, ‘Fast Life’, will be released on October 11 and Joe – who has previously dated a string of beauties including Taylor Swift, Demi Lovato and Ashley Greene – admits he was nervous about baring his soul and “putting it all out there” on a “personal” track about his love life.

He told “I wanted to be able to create something that spoke volumes about what I’ve gone through the past few years.

“‘I’m Sorry’ was the number one song that was really a lot to put on the table. It was a really personal song about something I was going through in a relationship. To put it all out there and just be that vulnerable is not always easy, but I was really happy with the outcome.”

However, Joe isn’t giving up on Jonas Brothers – his band with his siblings Nick and Kevin – and the trio will return with new music in the future.

He added: “With my brothers we’re definitely gonna create more music down the line. Right now we’re just focusing on our individual stuff. But we’ll definitely be doing it soon.”
