Which one is Britney's best video ever?

Britney Spears became just the second artist ever to debut multiple songs at No. 1 on the Hot 100 when her new single "Hold It Against Me" launched right at the top of the chart last week (Jan. 19). To say that the track's forthcoming video -- which she posted a still from yesterday (Jan. 24) -- is eagerly-awaited is a huge understatement. From the flirty school-girl mini-skirts of "...Baby One More Time" to the sweaty belly dancing of "I'm A Slave 4 U" to the Technicolor flight attendant look in "Toxic" to the steamy white bathing suit moves of "3," each one of Spears' clips has its own style.
