Black Eyed Peas singer Fergie discovered first-hand the method acting madness of her 'Nine' co-star Daniel Day-Lewis when she received love letters from the eccentric actor written as his character Guido. "Daniel is very charming. I'd go into my dressing room, and I'd find this little note. I'd open it, and it would be Guido's stationary. He would write me little notes as Guido. They were very cute and very charming," Fergie revealed at a press conference on November 15 at The Waldorf Astoria in New York.
