Man, you Britney fans are a surprising bunch!

We've pretty much given up trying to forecast the outcome of MTV News' Britney Spears Tournament: 30 Videos For 30 Years because as we go into the Final Four things look nothing like we expected … with one notable exception!

From the beginning, we had a feeling "I'm A Slave 4 U" would be one of the clips to survive the intense competition and we were right. The sexy clip marked a major transition in the Princess of Pop's career as she moved away from the wholesome image she'd carved out with her first two albums, …Baby One More Time and Oops! I Did It Again, and moved into more adult territory with her third album, Britney, and was one of her biggest "TRL" hits.

The other remaining videos indicate fans' affection for Britney Spears: Version 2011. Early on, we thought nostalgia would rule the day and her older videos would dominate the competition. That hasn't been the case as newer clips have proven themselves to be Britney fan favorites. So much so that two of the final four videos come from her most recent album, Femme Fatale. One of the biggest surprises of the whole competition – as far as the Britney experts here in the MTV Newsroom are concerned – has been the incredibly strong performance of Brit's latest clip "Criminal." It's a great video (and we know she loves it), but we are shocked that such a recent clip has destroyed Britney classics like "Baby" and "Stronger" to make it to the final four.

It's getting down to the wire and we only have three days and two rounds to go until Britney's big day. Our winner will be determined on Friday, Dec. 2 – Britney's 30th birthday! Cast your vote now through tomorrow, Dec. 1 at 7AM in the Final Four showdown after the jump.
