Lewis Hamilton's girlfriend Nicole Scherzinger clueless about Formula 1

Lewis Hamilton's popstar girlfriend Nicole Scherzinger has admitted that she is clueless when it comes to Formula 1.

The 31-year-old singer, who has been in an on-off relationship with the Mercedes driver for almost five years, has claimed that she is in "awe" of the sport.

"I am in awe of Formula 1 because there is so much money, technology and talent," the Daily Star quotes Scherzinger as saying. "But as for the racing, it really is like trying to understand rocket science when I'm there."

Hamilton will compete for Mercedes for the first time at the Australian Grand Prix later this month.
