The former Pussycat Dolls singer is living in the UK while judging 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 the 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. I was a real a**."
