"Womanizer," the fragrant pop star's lead single off upcoming album Circus, has officially become only her second hit to top Billboard's Hot 100 chart.

Brit-Brit's debut single"...Baby One More Time" was released exactly 10 years ago this month. A few months later it hit #1.

And though her somewhat-innocent pop princess days of yore are far behind her, she still has cause to feel nostalgic and celebrate this poptastic achievement.

Throw on your wig and grab a sundae, Britney—you've earned it!
