And then there were two! Fans have been voting in MTV News' Britney Spears Tournament: 30 Videos for 30 Years, and the 30 contenders have been narrowed down to the final two: "I'm a Slave 4 U," and "Criminal."
Voting in round four kicked off on Wednesday and by Thursday morning (December 1) "I'm a Slave 4 U" music video had breezed past Britney's Femme Fatale hit "Hold It Against Me" with 67 percent of the vote.
"Criminal," which features Britney's real-life boyfriend Jason Trawick had a tougher time, squeezing past younger Britney's big hit "Lucky" with a lead of only 53 percent in the final-four round.
Now, "Slave" and "Criminal" are battling it out for the title of best Britney Video of All Time; hundreds of thousands of votes were cast as the two clips made it through four competitive rounds.
Britney super fan and founder of BreatheHeavy.com, Jordan Miller, weighed in on why "Criminal" has made it this far, defeating the likes of "... Baby One More Time," "Stronger" and "I Wanna Go" in the process.
"I think 'Criminal' 's made it really far because it's her latest music video that's out," Miller told MTV News. "I think if that music video came out years ago, I don't think it would be doing so well. It's being promoted right now on TV and radio, but I think because it's new to fans, it's made it this far."
The final round of voting closes at 7 a.m. on Friday. Vote for your favorite video as many times as you would like; the winner will be announced tomorrow morning, which also happens to be Britney's 30th birthday!
