Could a couple of Joe Jonas's new songs be about his high-profile exes?

Jonas is about to release a solo album called 'FastLife,' and the singer says a track called 'I'm Sorry' "is one of those really honest songs about ending a relationship too early and you want them back in your life and all you can do is apologize.” Jonas didn't get specific about the inspiration for the song, but he's been in high-profile relationships with the likes of Taylor Swift, Demi Lovato, Camilla Belle and Ashley Greene.

The album also includes what Jonas describes as “a happy song about someone but then we ended up splitting up," which has also sparked speculation.

'FastLife' has drawn comparisons to Justin Timberlake's style, and Jonas says he's flattered: “He’s a fantastic artist," he says. "At the same time I feel like Justin Timberlake has his own lane and I’m trying to make something that is different and personal and not like anything else. Of course, it’s still a very big compliment.”

'FastLife' will be out October 11.
