Early lifeMiller was born in New York City on December 28, 1981. She moved to England as a child and attended the Heathfield school in Ascot, Berkshire and later studied for a year at the Lee Strasberg Institute with luminaries like Will Lee and Koni Summer in New York City.
Miller was born to hippie parents. Her father, Edward Miller, is an American banker born in Meadville, Pennsylvania. Her mother, Jo Miller, is a South African who ran Lee Strasberg's acting academy in London. Her parents parted when she was six years old, and her father subsequently married (and later separated from) the English interior designer Kelly Hoppen. Miller has one sister, Savannah, who is a fashion designer; two half-brothers, Charles and Steven, and one former step-sister, Natasha (daughter of Hoppen).
Career
Prior to her professional acting career, Miller worked as a photographic model. Following her appearance at the Glastonbury Festival in 2004, she was credited by many with having popularised the fashion style of boho-chic in Britain. Miller currently models for Pepe Jeans, and she posed for Vanity Fair magazine's 2006 Hollywood Issue topless and smoking a cigarette.
She had a recurring role in the television series Keen Eddie. Miller appeared in supporting roles in the 2004 remake of the 1966 movie Alfie as well as in Layer Cake (2004). She played the female lead opposite Heath Ledger in the period drama, Casanova (2005).
In 2005, Miller made her West End debut as Celia in Shakespeare's As You Like It. She played the role of Rosalind for one performance, when Helen McCrory, the actress playing the lead, fell ill.
She stars in Factory Girl, a film about 1960s socialite and Andy Warhol's muse Edie Sedgwick that opened December 29, 2006. Although the film has been deemed controversial, her performance has received acclaim.
Miller has several high-profile projects due out in the next year. In 2007, she stars opposite Michelle Pfeiffer and Robert DeNiro in the fantasy epic Stardust, and opposite James Franco in the horror comedy Camille, as well as Interview directed by Steve Buscemi.
Miller recently completed work on the film version of writer Michael Chabon's novel, The Mysteries of Pittsburgh, also starring Peter Sarsgaard. The project is slated for a 2007 release. In an interview for Rolling Stone magazine Miller made derogatory comments about the city, referring to Pittsburgh as "Shitsburgh". She apologized, noting that her father grew up in Western Pennsylvania only 85 miles from the city. However, Miller was forced to retract her profane comment by the film's producers. Her apology was damage control, Miller told the Guardian, and in her opinion calling the city "Shitsburgh" was not a big deal.
Miller has lent her support to design limited edition T-shirts or vests for the 'Little Tee Campaign' for Breast Cancer Care which donates money for breast cancer research.[6] She has also agreed to design a range of jeans for Pepe.[citation needed]
Miller has also supported Breast Cancer Haven's Lend a Hand, Raise a Grand Appeal which asks people to raise £1,000 in one year for Breast Cancer Haven, which runs centers offering a free program for support, information and complementary therapies to anyone affected by the disease. She encouraged others to take part, saying "The Lend a Hand, Raise a Grand appeal is your chance to support a fantastic charity. It is a chance for you to make a difference -- a little bit of effort goes a long way with this unique initiative. We are all affected by breast cancer so please, please support it." Miller is also an ambassador for the Starlight Childrens Foundation.
Miller started a fashion company with her sister Savannah. The company, Twenty8Twelve, gets its name from Sienna Miller's date of birth.
Personal life
Miller's relationship with Jude Law has been frequently featured in the entertainment press. On Christmas Day of 2004, they became engaged. However, on July 18, 2005, Law issued a public apology to her for having an affair with Daisy Wright, the nanny of his children by his former wife (actress Sadie Frost). At the same time, Miller was rumored to be having an affair with Law's friend, Daniel Craig.[7][8] Despite attempting to salvage their relationship, Miller and Law separated. They reunited briefly in 2006, before again separating.[9] In January of 2007, Miller was spotted being taken to her hotel in the early morning hours by P. Diddy after a night of partying.[10] Another video appeared in April 2007 showing some of her posse harassing a paparazzo after, it is alleged, she left a club several minutes after Combs. [11].
