Nicole Scherzinger Pulls Out of F1 Rocks Concert in Singapore

Pussycat Dolls lead singer Nicole Scherzinger is said to have pulled out of the inaugural F1 Rocks Concert in Singapore 2 weeks before the event because she has broken up with world champion Lewis Hamilton.

She is due to host the F1 Rocks Concert in Singapore introducing performers like Beyonce and the Black Eyed Peas.

But a source told the tabloid that Hamilton has ended the relationship due to the pressure on him to get married.

"The last thing Nicole wanted to be doing is anything to do with formula one now -- so she immediately pulled out of F1 Rocks," the source said.
