Miley Cyrus (born Destiny Hope Cyrus; November 23, 1992) is an American actress and singer-songwriter. She is the daughter of country singer Billy Ray Cyrus. She made her debut in three episodes of the series Doc before appearing in a minor role for the film Big Fish in 2003. In 2006, she was established as a teen idol with the success of the Hannah Montana franchise, a former Disney Channel sitcom in which she portrayed the role of Miley Stewart and Hannah Montana. Cyrus later recorded numerous songs for the soundtrack of the first season. She later signed a deal with Hollywood Records and released the joint album Hannah Montana 2: Meet Miley Cyrus. The album served as both a soundtrack and Cyrus' debut album, and went on to sell over three million copies in the US alone. The album also spawned the Top 10 hit "See You Again" and the less successful "Start All Over". To promote the album, Cyrus embarked on the Best of Both Worlds Tour, which was later adapted into the 2008 film Hannah Montana & Miley Cyrus: Best of Both Worlds Concert. Cyrus released her first solo album, Breakout, in 2008. The album became her third to top the Billboard 200, and was certified Platinum by the RIAA. Breakout featured the successful singles "7 Things" and "Fly on the Wall".
That same year, she launched her film career by appearing as the voice of Penny in the animated film Bolt; she earned a nomination for the Golden Globe Award for Best Original Song for her performance of its theme song, "I Thought I Lost You". In 2009, she starred in the feature film Hannah Montana: The Movie. The film's soundtrack introduced Cyrus to audiences within country and adult contemporary markets. It also featured the hit single "The Climb", which went on to become one of Cyrus' most successful singles to date. With the release of her extended play The Time of Our Lives that same year, she began to cultivate an adult image and developed a more mainstream pop sound. It spawned the highly successful single "Party in the U.S.A.", which went on to become Cyrus' highest peaking single on the Billboard Hot 100 to date. Cyrus further adapted a mature image with the release of the film The Last Song and her third studio album, Can't Be Tamed. The album incorporated more dance elements than her previous efforts, and subsequent performances featured a more sexual theme. Following the album's release, Cyrus chose to focus on her film career. In 2011, she appeared in the drama film LOL alongside Demi Moore. The film featured themes of teenage rebellion and saw Cyrus' character using drugs and drinking. LOL received a limited release, and failed to make back it's budget. She later appeared in the direct-to-video film So Undercover along with Kelly Osbourne. In 2012, it was confirmed that Cyrus had begun working on her fourth studio album, and later signed a deal with RCA Records to distribute the project. It is currently slated for release in 2013.
Since her debut, Cyrus has become one of the most successful artists to originate from Disney. Cyrus ranked number thirteen on Forbes' 2010 Celebrity 100.
For the 2011 Guinness World Records, she was named the Most Charted Teenager following her 29th US Billboard Hot 100 chart entry on November 7, 2009 with Party in the USA. She has attained a total of six Top 10 hits on the Billboard Hot 100, and had five RIAA certified albums by the age of 18.
