That kiss is probably one of the most iconic moments in television history. Beyonce's reveal was memorable, but it doesn't touch Madonna/Britney/Christina.
The kiss. It's an iconic moment in both Britney's and Madonna's careers (not really in Xtina's though). It will be remembered for years as one of the biggest VMA moments ever.
Beyoncé's baby bump was cute but people will forget it within a year or two.
