Kanye West's Taylor Swift showdown tops craziest MTV VMA moments

Kanye West's outburst in the middle of Taylor Swift's acceptance speech at the 2009 MTV Video Music Awards has topped a list of the craziest moments at the annual prizegiving.

The rapper stunned fans when he stormed the stage to express his outrage after his pal Beyonce lost to Swift in the Best Female Video category - and staff at Billboard.com have named the unscripted moment as one of the most memorable to go down at the event.

Beyonce's pregnancy announcement following her performance at the 2011 show, Madonna's steamy smooch with Britney Spears in 2003, and Courtney Love crashing an interview with Madonna in 1995 were also named as wacky highlights.

The rundown, compiled ahead of the 2013 ceremony on Sunday (25Aug13), also includes "Britney's flab dance" in 2007; Billboard editors describe Spears as "un-toned and noticably unprepared" and "looking almost like a zombie" during the awkward show opener.
