Nicole Scherzinger thought Tony Blair was still Britain's Prime Minister

Washington, Nov 1 (ANI): Nicole Scherzinger was left red-faced after she failed to recognise Britain's Prime Minister at a recent awards function in London.

The former Pussycat Dolls singer admits that she may need to update herself on British politics after the embarrassing mix-up.

Formula One ace Lewis Hamilton's girlfriend was introduced to Mr Cameron at the Mirror's Pride of Britain Awards but didn't have a clue who he was.

She even asked one of his aides the whereabouts of Tony Blair - who she thought was still in charge.

"Who's David Cameron?," Contactmusic quoted her as telling the Daily Mirror.

"Oh, the Prime Minister! I didn't know who he was.

"They said they were introducing me to the Prime Minister and he came over, and I was like, 'Where's Tony Blair?' I thought it was still him. Someone had to tell me. I was a real a**, she added. (ANI)
