The 45 year old singer was terrified when he took to the stage to perform as he thought people might hate his voice.
He said: "Music was my escape. I remember being petrified the first time I sang. I closed my eyes, sang, and everyone clapped afterwards. That gave me such a buzz that my fears melted away. From then on, I kept coming back."
Seal has also revealed he now takes inspiration from his family wife Heidi Klum, their sons Henry, three and 23 month old Johan as well as Heidi's daughter Leni, four, with Formula One mogul Flavio Briatore when writing music.
The singer says 35 year old supermodel Heidi is his "best friend", adding he fell in love with her so quickly he didn't mind when she told him she was pregnant by her ex-boyfriend one month into their relationship.
He told Britain's Daily Mail newspaper: "I was taken aback when I met her. I thought she was one of the most beautiful women I'd seen. I thought, 'Wow! Whoever goes out with that girl is one lucky guy!'
"A month into our relationship, she told me she was pregnant, but was no longer with the father. I told her it didn't change the way I felt about her. "Apart from being my wife, she's also my best friend."
