This former Mickey Mouse Club member was on top of the world until about 2003/2004, when she released her fourth ablumn and married Kevin Federline. They then started a family, having two children almost back to back. Britney still put out ablumns, but they were mainly compliations of her former songs and remixes.
In 2007 Spears and Federline filed for divorce, causing a huge media frenzy over the custody of their children, drug abuse problems, and emotional and eratic behavior from Britney. At this time, Britney decided to have her "comeback" at the MTV Awards, which failed miserably, causing bad reviews and an unfavorable position for the former pop-star.
