With her baby doll sexuality and infectious dance tracks, Britney Spears became the definitive pop princess of the late 1990s, ushering in a new era of bubble gum music for an entire generation of young fans. Pretty, talented and incubated on performance hothouses like "Star Search" (CBS, 1983-2004) and "The Mickey Mouse Club" (The Disney Channel, 1989-1994), Spears was groomed for fame from her earliest years. In 1998, she exploded on the pop music scene with her smash hit single " Baby One More Time," which preceded a series of hit singles, sold-out concerts, TV specials and even a feature film, "Crossroads" (2002), all of which made her an ubiquitous pop culture presence. By 2004, however, Spears was becoming overshadowed by her increasingly bizarre personal travails covered relentlessly in the tabloids. She had married and divorced former back-up dancer Kevin Federline, given birth to two children, entered rehab, lost custody of her children and been twice admitted to a psychiatric ward for involuntary observation. Then, defying the odds, a more mature Spears gradually began making her comeback with two more multi-platinum albums - Circus (2008) and Femme Fatale (2011). To most observers, her 2011 engagement to boyfriend Jason Trawick and signing on to judge "The X Factor" (Fox, 2011- ) alongside Simon Cowell signaled calmer waters ahead. Regardless of her struggles to stay relevant and grounded during her time at the top, there was no denying Spears' stature as one of contemporary music's more popular and beloved entertainers.
