In 2001, she released her third studio album Britney and expanded her brand, playing the starring role in the film Crossroads. She assumed creative control of her fourth studio album, In the Zone released in 2003, which yielded chart-topping singles "Me Against the Music", "Toxic" and "Everytime". After the release of two compilation albums, Spears experienced personal struggles and her career went under hiatus. Her fifth studio album, Blackout, was released in 2007 and despite receiving little promotion, it spawned hits "Gimme More" and "Piece of Me". In 2008, her erratic behaviour and hospitalizations caused her to be placed in a conservatorship. The same year, her sixth studio album Circus was released, with the global chart-topping lead single "Womanizer". After embarking on The Circus Starring Britney Spears, she released greatest hits The Singles Collection, which featured U.S. and Canadian number-one single "3".
