2007–08: Meet Miley Cyrus and Breakout

The second season of Hannah Montana premiered on April 23, 2007, and ran until October 12, 2008.^[52] Shortly afterwards, Cyrus signed a four-album deal with Disney-owned Hollywood Records.^[53] On June 26, 2007 Cyrus released the double-disc album Hannah Montana 2: Meet Miley Cyrus.^[54] The first disc was the soundtrack to the second season of Hannah Montana, while the second disc served as Cyrus' debut studio album. The album debuted at number one on the Billboard 200 with first week sales of 326,000 copies.^[55] The album went on to be certified certified three times platinum by the Recording Industry Association of America.^[56] The album spawned the single "See You Again", which served as Cyrus' first single as a solo artist. The song quickly became a hit, and became her first Top 10 hit on the Billboard Hot 100 chart.^[57] It was eventually certified Platinum in the country, making it her first single to be RIAA certified.^[58] The single also had success in countries such as Australia and Canada, where it also peaked inside of the Top 10.^[59][60] The album's second single, "Start All Over", was released in early 2008. The single failed to match the success of its predecessor, debuting and peaking at number 68 on the Hot 100 chart.^[61][62] Numerous songs from the Hannah Montana portion of the album charted worldwide following its release.^[63][64][65]

Cyrus performing on the Best of Both Worlds Tour

During the fall of 2007, Cyrus launched the Best of Both Worlds Tour to promote the joint album. With the Jonas Brothers, Aly & AJ, and Everlife as her opening acts, Cyrus toured from October 17, 2007, to January 31, 2008, with stops in the U.S. and Canada.^[66] Tickets sold out in minutes and were scalped for up to $2,500 and an average of $214, well above their $26–$65 face value.^[67] A Ticketmaster official commented, "People who have been in this business for a long time are watching what's happening, and they say there hasn't been a demand of this level or intensity since The Beatles or Elvis."^[68] After the end of the Best of Both Worlds Tour in January 2008, Walt Disney Pictures released Hannah Montana & Miley Cyrus: Best of Both Worlds Concert, a 3D concert film of the tour, on February 1, 2008, for what was expected to be a one-week run. The film earned over $31 million^[69] at the box-office and an average of $42,000 per theater, twice the expected total, convincing Disney executives to extend the release for an indefinite run. "We don't want to turn away kids from the theaters who couldn't get into the concerts," said Chuck Viane, Disney's chief of distribution.^[70] The film's soundtrack was released by Walt Disney Records and Hollywood Records on March 11, 2008, and peaked at number three on the Billboard 200.^[71]
In February 2008, Cyrus and her friend Mandy Jiroux opened a YouTube account and began posting videos of what they called The Miley and Mandy Show. The show, described as a "YouTube hit", is said to be filmed for fun by Cyrus and Jiroux and to be entirely their work, with Cyrus and Jiroux editing the footage together.^[72] In May 2008, Gossett, Cyrus's longtime acting agent, left Cunningham Escott Slevin Doherty for United Talent Agency, partially with the hope of "giving Cyrus the major-agency backing that would support a widening career", according to The Hollywood Reporter.^[36][73] About a year later in June 2009, Cyrus left both Gossett and UTA, which had recently negotiated her deals for The Last Song and the fourth season of Hannah Montana, and joined the Creative Artists Agency, which had already represented her for music.^[74] Nikki Finke, who broke the news, reported, "Is this fair to UTA? Of course not. But I hear the decision was made by Miley's mother Trish [sic] Cyrus".^[75] Cyrus celebrated her 16th birthday at Disneyland with a charity fundraiser for Youth Service America, a youth volunteer service organization.^[76][77][78]
On July 22, 2008, Cyrus released her second studio album under her own name, titled Breakout. Cyrus said Breakout was inspired by "what's been going on in my life in the past year."^[61] Cyrus co-wrote eight out of twelve songs on the album.^[61] "Songwriting is what I really want to do with my life forever, [...] I just hope this record showcases that, more than anything, I'm a writer."^[79] Breakout debuted at number one on the Billboard 200 with first week sales of 371,000 copies.^[80] This made it Cyrus' highest first week sales to date, and gave Cyrus her third number one album on the chart. The album went on to receive a Platinum certification from the RIAA, denoting sales of one million copies.^[56] Breakout was preceded by the lead single "7 Things", which became her second single to reach the Top 10 of the Billboard Hot 100.^[62][81] The album's second single, "Fly on the Wall", failed to have the same success, peaking at number 84 on the Hot 100.^[82] It was, however, successful in the United Kingdom, peaking at number 16 on the singles chart.^[43] Cyrus hosted the 2008 CMT Music Awards with her father in April^[83] and the 2008 Teen Choice Awards by herself in August.^[84] In 2008, Cyrus provided the voice of Penny in the 2008 computer-animated film Bolt, which was released on November 21, 2008, to critical acclaim.^[85] Cyrus also co-wrote and recorded the song "I Thought I Lost You" as a duet with John Travolta for the film, for which she received a Golden Globe nomination.<sup>[86]
