Britney Spears was just 16 years old when she made her debut on the Billboard Hot 100 singles chart on Nov. 21, 1998 with the now classic "... Baby One More Time." The song shot to No. 1 less than two months later and the rest was history. 

To celebrate the singer, we've compiled the 20 biggest Britney Spears songs on the Billboard Hot 100.

This chart of Spears' 20 Biggest Billboard Hot 100 Hits is based on actual performance on the weekly Billboard Hot 100, through the chart dated Dec. 24, 2016. Songs are ranked using an inverse point system, with weeks at No. 1 earning the greatest value and weeks at No. 100 earning the least.

19. "Work B***h"
Hot 100 Peak Position: 12 (2013)
"Work B***h," the lead single off Britney's eighth studio effort Britney Jean, peaked at 12 on the hot 100 and told fundamental truths -- if you want to look like Britney, drive like Britney and be as successful as Britney, you better work, b---h.

9. "Toxic"
Hot 100 Peak Position: 9 (2004)
For the second single off 2004's "In the Zone," Britney went with something a little different, sonically-speaking. "Toxic" went to places previously unexplored by Spears: aggressive electronic sound effects, shrieking strings and a killer surf-guitar riff. The unlikely combo, ushered in by steamy vocals, worked, as "Toxic" burned into the Hot 100's top 10.
