Katy Perry won the award for best female singer at the 2013 MTV EMA music awards in Amsterdam on Sunday, pipping Lady Gaga and Miley Cyrus to the post and collecting her third EMA prize in the process. With the three pop divas in contention, the prize for best female was the most closely watched battle at the Viacom-owned music network's 20th annual European awards ceremony. Cyrus, who was awarded best video for "Wrecking Ball", capitalized on her infamous "twerking" encounter with musician Robin Thicke at the U.S. Video Music Awards in August, walking the red carpet in a bold mini dress with the words "Please Stop Violence" wrapped tightly around her hip. British-Irish boy band One Direction had a good night, taking the prize for best pop, while Harry Styles, known as much for his singing in the band as for his celebrity girlfriends, was awarded best style.
