The Formula One star has been collaborating with London singer-songwriter Angel on new songs, but a source close to him insisted that he isn't going to launch a pop career.
"I've been doing a lot of writing for different people. The last couple of days I've been working with Lewis," Angel told The Sun. "He's doing his thing right now."
A source added: "Lewis uses the studio as a way of letting off steam away from the track. He's very passionate about music and wants his work to be of good quality.
"He's got the cash so why not? His management will start to worry if his dedication to music takes precedence over F1. But he has no intention of becoming a popstar."
Hamilton's girlfriend Nicole Scherzinger currently serves as a judge on The X Factor in the UK.
