Nicole Scherzinger was left red-faced on Monday (29Oct12) after she failed to recognise Britain's Prime Minister at an awards ceremony in London.
The former Pussycat Dolls singer is living in the U.K. while judging the country's version of The X Factor, but admits she may need to brush up on British politics after the embarrassing mix-up.
Scherzinger was introduced to Prime Minister David Cameron at the Pride of Britain Awards, but didn't have a clue who he was and even asked one of his assistants where former leader Tony Blair was.
She tells Britain's Daily Mirror, "Who's David Cameron? 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."
