Pump up the volume: Hamilton makes singing debut!

Lewis Hamilton's infatuation with the world of music has been well chronicled, but the four-time world champion has now taken the bold step of making his singing voice known - although in stealth mode.

Hamilton - who performs under the pseudo XNDA - has added a bit of his suave lyrical self to mega-pop star Christian Aguilera's latest cut untitled "Pipe".

The Mercedes driver, speaking to the media in Austria on Thursday, remained guarded on the usbject of his musical debut, refusing to acknowledge his presence on the recording.

"In the last race I was like it’s not something I really want to speak about. I’m here to focus solely on trying to win the championship," he said.

The breezy cool track, and beat, is a main feature on Aguilera's new album - apparently her first in six years.

As a footnote, the award winning singer, song writer, actress and TV personality paid Hamilton and the F& paddock a visit in Baku earlier thus year.

Check out the track, and listen carefully at the 2:40 mark, and tell us what you think!

Phillip van Osten

Motor racing was a backdrop from the outset in Phillip van Osten's life. Born in Southern California, Phillip grew up with the sights and sounds of fast cars thanks to his father, Dick van Osten, an editor and writer for Auto Speed and Sport and Motor Trend. Phillip's passion for racing grew even more when his family moved to Europe and he became acquainted with the extraordinary world of Grand Prix racing. He was an early contributor to the monthly French F1i Magazine, often providing a historic or business perspective on Formula 1's affairs. In 2012, he co-authored along with fellow journalist Pierre Van Vliet the English-language adaptation of a limited edition book devoted to the great Belgian driver Jacky Ickx. He also authored "The American Legacy in Formula 1", a book which recounts the trials and tribulations of American drivers in Grand Prix racing. Phillip is also a commentator for Belgian broadcaster Be.TV for the US Indycar series.
