The title-tract of Spears debut album and its accompanying music video also established her as a international sex symbol, garnering controversy over the influence of her public image on teenage girls. Amidst further media scrutiny, Spears continued her career with three more consecutive number one studio albums; Oops!… I Did It Again (2000), Britney (2001), and In the Zone (2003).[4][5] Spears subsequently became the first artist in the history of Nielsen SoundScan to have four consecutive albums debut at number one. Spears’s personal life began to gain substantial media attention after her marriage to Kevin Federline in 2004. Their marriage ended two years later, resulting in an ongoing custody battle over their first child, born in 2005 and their second child, born in 2006.[6][7]
