Lady GaGa is influenced by "perfect" Paris Hilton's cleanliness. The 22-year-old 'Just Dance' singer - who went to the Convent of the Sacred Heart School in New York with Paris and Nicky Hilton - has admitted the well-presented socialite sisters have had a big effect on her appearance. 

GaGa - whose real name is Stafani Joanne Germanotta - told Britain's Daily Mirror newspaper: "Paris and Nicky Hilton went to my school.

"They're very pretty, and very, very clean. It's impressive to be that perfect all the time. In commercial terms, they've been quite an influence on me."Stefani - who used to be a go-go dancer - has been spotted strutting around London in freezing temperatures this week wearing skimpy hot pants and corsets while she promotes her chart-topping track 'Just Dance'.

Rather than covering up, she said: "Look at me - I'm fiercely tanned and very orange!"After leaving school, Lady GaGa worked as a burlesque dancer before writing songs for Britney Spears and the Pussycat Dolls - who she is touring with in the UK.

The eccentric singer said: "Even though I sing about panties and pornography and fame, I take it all very f***ing seriously."I want people to think, 'Every time I have this b***h nailed down, she does something different.' "
