The 33-year-old Maroon 5 frontman once met "the most beautiful girl" at a petrol station - who later became the subject of the band`s first album `Songs About Jane` - and tried to woo her by writing a song and having it played into her workplace.

He said: "If I really liked a girl and I felt these romantic feelings towards her, I would literally write a song and make sure they heard it. I was so bold."

But unfortunately the romance was short-lived and a broken-hearted Adam decided to pour his pain into the 2002 album.

He told Paperbag: "It was a brief relationship but we really did fall in love with each other and when we broke up, my heart was broken.

"I didn`t have money or a job. All I had was a girl I was in love with and the dream of being a famous musician. I was like, `I need to turn this into something good or it`s going to be a bad thing?."

With a new album in the pipeline, as well as a new fragrance and a judging slot on `The Voice`, Adam admits that while he is happy to be working, he doesn`t always plan to be so busy.

He said: "I just hope this isn`t the case when I`m 40. I turned 33 and I thought, `OK, this is exactly where I need to be`, and why should I stop until I get to a point where I can, and say, `f**k this, I`m going to go play golf?."
