Cyrus was born in Nashville, Tennessee as Destiny Hope Cyrus on November 23, 1992, to parents Leticia "Tish" (née Finley) and country singer Billy Ray Cyrus. Cyrus has five siblings. Her elder siblings Trace and Brandi Cyrus are Tish's children from a previous relationship, whom Billy Ray adopted when they were very young. Trace is a vocalist and guitarist for the electronic pop band Metro Station, while Brandi has played guitar for Cyrus's concerts and formed a band with The Secret Life of the American Teenager star Megan Park. Cyrus attended Heritage Middle School, where she was a cheerleader. She currently attends school at Options For Youth Charter Schools and studies with a private tutor on the set of her TV show. Cyrus grew up on her parents' farm outside of Nashville where she regularly attended the People's Church.
Cyrus became interested in acting when she was nine, and took classes at the Armstrong Acting Studio while her family lived in Toronto, Canada. Her early career was marked by minor roles, the first of which was playing a girl named Kylie on her father's television series Doc. In 2003, Cyrus was credited under her birth name for her role as "Young Ruthie" in Tim Burton's Big Fish. Dolly Parton, Miley's godmother, advised Cyrus's mother to sign Cyrus with Morey Management Group, which The Hollywood Reporter said "was the best advice she could [have gotten] on who should rep her daughter". The group's leader, Jim Morey, and his son, Jason, began co-managing Cyrus's career alongside Tish Cyrus.
Hannah Montana first aired on March 24, 2006 in the United States and averaged more than 4 million viewers per episode. As the star of Hannah Montana, Cyrus became popular with children and teenagers, leading to a successful career in music. Her recording debut was on April 4, 2006, when the fourth edition of Disney Mania was released. Cyrus sang a cover of James Baskett's "Zip-a-Dee-Doo-Dah," originally from the 1946 animated film Song of the South. On October 24 the same year, Walt Disney Records released the first Hannah Montana soundtrack. Of the nine tracks on the album performed by Cyrus, eight were credited to Hannah Montana and one, a duet with Billy Ray Cyrus titled "I Learned from You", was credited to Cyrus as herself. The album debuted at #1 on the US Billboard 200 and sold 281,000 copies in its first week, beating such artists as John Legend and rock band My Chemical Romance.
On April 25, 2008, the televised entertainment program Entertainment Tonight reported that Cyrus had posed topless for a photoshoot with Vanity Fair.[93] The photo, and subsequently released behind-the-scenes photos, show Cyrus with her bare back exposed but her front covered with a bedsheet. The photoshoot was taken by photographer Annie Leibovitz. The full photograph was published with an accompanying story on The New York Times' website on April 27, 2008. On April 29, 2008, The New York Times clarified that though the pictures left an impression that she was bare-breasted, Cyrus was wrapped in a bedsheet and was actually not topless. Some parents expressed outrage at the nature of the photograph, which a Disney spokesperson described as "a situation [that] was created to deliberately manipulate a 15-year-old in order to sell magazines." Gary Marsh, president of entertainment for Disney Channel Worldwide, was quoted by Portfolio magazine to have said, “For Miley Cyrus to be a ‘good girl’ is now a business decision for her. Parents have invested in her a godliness. If she violates that trust, she won’t get it back.”
In response to the Internet circulation of the photo and ensuing media attention, Cyrus released a statement of apology on April 27, 2008: "I took part in a photo shoot that was supposed to be 'artistic' and now, seeing the photographs and reading the story, I feel so embarrassed. I never intended for any of this to happen and I apologize to my fans who I care so deeply about." Leibovitz also released a statement: "I'm sorry that my portrait of Miley has been misinterpreted. The photograph is a simple, classic portrait, shot with very little makeup, and I think it is very beautiful." On April 28, 2008, Vanity Fair published their full interview and photo shoot with Cyrus and her father Billy Ray Cyrus, as well as the behind-the-scenes photographs, on their website. According to the interview, Cyrus's parents or minders were present during the entire duration of the photo shoot. The idea to pose with the sheets on was suggested by Leibovitz. When asked if she was "anxious" about the pose, Cyrus stated to interviewer Bruce Handy: "No, I mean I had a big blanket on. And I thought, this looks pretty, and really natural. I think it's really artsy. It wasn't in a skanky way.... And you can't say no to Annie. She's so cute. She gets this puppy-dog look and you're like, okay." On December 2, 2008, TV Guide reported that Cyrus is interested in working with Leibovitz again in the future and is even considering a career in photography for herself, "That's what I want to do with my life. I would love to be a photographer... I want to come to London to study. I hear there are some great art schools here so I would love to do that."
Cyrus's performance of "Party in the U.S.A." at the 2009 Teen Choice Awards on August 10 incited controversy. Critics of the performance complained that she danced provocatively alongside a dance pole that was on top of an ice-cream pushcart, and that another part of the performance seemed to poke fun at American culture. Some drew negative comparisons to Britney Spears, though Cyrus herself welcomed comparisons to the former teen pop star. Others defended Cyrus, arguing that still images of the performance made it seem more lewd than it actually was, and opining that the ensuing controversy took the focus away from the six awards she won that night. Others observed that Cyrus already had a risque image, and sought to broaden her appeal to audiences, with the performance a part of her transition into an entertainer for older audiences, much as had been observed years earlier with Britney Spears. Cyrus's label, Hollywood Records, and The Walt Disney Company, which produces Hannah Montana, offered no comment on the performance, though Disney asserted that all performances on the Disney Channel are appropriate for children age 6 – 14. The Fox Network, which broadcast the awards, also offered no comment, other than to confirm that the performance would be included in its broadcast of the ceremony.
