Born on December 28, 1982, in New York.
Sienna Miller returned to New York after graduating from Heathfield to study acting full time at the Lee Strasberg Institute. She performed in numerous NYC productions, including “A School for Scandal” by British playwright Richard Brinsely Sheridan and “Cigarettes and Chocolate” by writer/director Anthony Minghella. Sienna made the jump to television with her role as Fiona Bickerton on “Keen Eddie”, where she played a British woman forced to live with an NYPD detective (Valley), who is on the trail of a drug dealer he let get away back in the States.
Sienna was also cast in a remake of the 1966 comedy classic, “Alfie” (2004). She played one of many women seduced by Alfie (Jude Law) and Sienna's performance was singled out as one of the remake's finer elements.
Miller and Law spent most of the shoot avoiding the paparazzi, who smelt a story once they realized the two stars were together, despite Law being in the midst of divorce proceedings with actress Sadie Frost.
In 2005 her fiancé Law made a public admission of infidelity, apologizing for an affair with his children's nanny. The couple's seemingly on-again, off-again relationship captivated the press for several months in 2005
In the short time that Sienna Miller has been an actress, the 5’6” slender blonde from New York has attracted a lot attention. However, much of the attention has not focused on her acting abilities but on her relationship with Jude Law.
