Over the past 12 years, there have been some really great pop performances during the Super Bowl's annual halftime extravaganza. With Beyonce confirmed as the upcoming Super Bowl halftime diva for Feb. 2013, we want to take a look back at the other pop stars who have come before her and for you readers to weigh in on your favorite Super Bowl performer of the 21st century (so far, at least).

In 2000, Christina Aguilera and Enrique Iglesias took the stage during Super Bowl XXXIV halftime to perform a medley of celebratory songs in honor of the new millenium... That seems so long ago! Remember all of the Y2K hubbub? But we digress! Along with live music from co-performers Phil Collins and Toni Braxton, as well as accompaniment from a massive choir, Xtina and Enrique sang a pitch-perfect duet to a track called 'Hands on the Future.'

One year after Xtina performed during the Super Bowl, her pop princess counterpart Britney Spears performed along with 'N Sync, Mary J. Blige and Nelly -- oh yeah, and these dudes called Aerosmith. 'N Sync were actually co-headlining with the rockers -- the boy band performed their hits 'Bye, Bye, Bye' and 'It's Gonna Be Me' -- and Brit's arrival during the entire group's performance of 'Walk This Way' was the climactic event of the show.

Two years later, in 2003, No Doubt were the show's big act along with former Police frontman Sting and country vixen Shania Twain. After a country-pop intro from Twain, Gwen Stefani, Tony Kanal, Adrian Young and Tom Dumont hopped onstage to bring a dose of '90s nostalgia with the pop-punk anthem 'Just a Girl.' Stefani also teamed up with Sting for the closing song, the Police's 1979 classic 'Message in a Bottle.'

Next up is perhaps the most infamous Super Bowl halftime show of all-time, 2004's live show featuring Janet Jackson, Diddy, Nelly, Kid Rock and of course, the boobie-exposing Justin Timberlake. After Ms. Jackson sang falsetto on 'All for You' and took us back to her early days with 'Rhythm Nation' -- Nelly also performed 'Hot in Herre' and while Diddy entertained with 'Mo Money Mo Problems' -- JJ and JT shocked the world during 'Rock Your Body' with their obviously intentional "wardrobe malfunction."

In 2007, Prince dominated the halftime show solo during Super Bowl XLI. The High Priest of Pop rocked the crowd, shredding to a medley of uptempo hits like 'Let's Go Crazy' and 'Baby I'm a Star' before closing it out with an epic rendition of the always epic ballad 'Purple Rain.' His Royal Badness also took on Tina Turner, Foo Fighters and Jimi Hendrix with covers of 'Proud Mary,' 'Best of You' and 'All Along the Watchtower,' respectively.

Black Eyed Peas were the next piece of pop power to grace the Super Bowl stage, as the quartet entertained the crowd along with Usher during 2011's XLV Halftime spectacular. Opening with 'I Gotta Feeling,' the group then segued into 'Boom Boom Pow' before Fergie Ferg sang 'Sweet Child O' Mine' with Slash on guitar. 'Pump It,' 'Let's Get It Started,' 'Where Is the Love?,' and 'The Time (Dirty Bit)' were also performed live before Usher surprised everyone, dancing along to his club banger 'OMG.'

Most recently, in 2012, the Material Girl herself, Madonna, performed live at the Super Bowl for the first time in her career. Her intro was completely insane, belting out 'Vogue' on a completely illuminated stage before giving way to 'Music' and her LMFAO party time (the duo came out to perform 'Party Rock Anthem' and 'Sexy and I Know It' with Madge stop their shoulders). 'Give Me All Your Luvin'' saw Nicki Minaj and bird-flipping cheerleader M.I.A. joining Madonna, and the entire show closed with a bang as Cee Lo Green came out for 'Open Your Heart,' 'Express Yourself' and 'Like a Prayer.'
