Britney Spears Video Tournament Down To Final Four!

Voting in round three of MTV News' Britney Spears Tournament: 30 Videos for 30 Years has officially closed and we're now down to the Final Four. Will "Lucky" get lucky against the naughtier "Criminal" video? Will "Hold It Against Me" get served by "I'm a Slave 4 U"? Second-round voting is now open so you can help decide.

At the end of round three, "Lucky" pushed ahead of "Till the World Ends" at the last minute, beating the newer video by less than 0.5 percent of the vote. And although "Stronger" held the lead for most of the third round, "Criminal" overpowered the 2000 video late Tuesday night.

Britney's collaborator on "Me Against the Music," Madonna, officially exited the tournament after the duet fell to "Hold It Against Me," which also came as a last-minute surprise since the Brit/Madge collabo held the advantage for most of round three.

In perhaps the most competitive pairing of the third round, two of Britney's widely celebrated videos, "Toxic" and "I'm a Slave 4 U" were pitted against each other, but sweaty Britney out-danced double-agent Britney. MTV News' Britney video experts have already predicted that "Slave 4 U" will be the biggest threat in the Final Four.

Voting for the top four clips is open until 7 a.m. Thursday; the top two will be unveiled at 10 a.m. on Thursday morning, followed by the big reveal of the winner at 10 a.m. ET on Friday, which happens to be Britney's 30th birthday.

Britney Spears' Boyfriend Ready to Pop the Question

Spears, who turns 30 on Friday, "is having one of the best times of her life," according to a source, and the couple has talked "about marriage for a long time. It would be surprising if they are not engaged by the end of the year."

Trawick, 39, and Spears have been a hot item for two years, and according to a Spears family insider, "Jason adores her two sons, Sean Preston and Jayden James. Jason is planning on taking Britney on a secluded getaway once her "Femme Fatale" tour wraps, and it's very likely he will pop the question at that time."
