Ashley Michelle Tisdale is an American actress and singer. During her childhood, she was featured in over 100 advertisements and had minor roles in television and theatre. She achieved mainstream success as Maddie Fitzpatrick in the Disney Channel teen sitcom The Suite Life of Zack & Cody (2005–2008). This success was heightened when she starred as Sharpay Evans in the High School Musical film series (2006–2008). The success of the films led to Tisdale's signing with Warner Bros. Records and subsequently releasing her debut studio album, Headstrong (2007), which was a commercial success, earning a gold certification from the Recording Industry Association of America (RIAA). Tisdale played the voice role of Candace Flynn in the Disney Channel animated series Phineas & Ferb (2007–2015).
Tisdale's second studio album, Guilty Pleasure (2009), was released to less commercial success than its predecessor. Tisdale would part ways with Warner Bros. Records following the release of the album. During this time, she began appearing in more films and returned to television with shows such as Hellcats (2010). Tisdale's production company Blondie Girl Productions, first formed in 2008, signed a multi-year production deal with Relativity Media in 2010; Tisdale would produce shows such as Miss Advised (2012) as part of the deal. Tisdale starred in the High School Musical spin-off film Sharpay's Fabulous Adventure (2011), also releasing a soundtrack to promote the film.
In 2013, Tisdale announced work on her third studio album, releasing the promotional single "You're Always Here", and starred in the horror comedy film Scary Movie 5.
