Justin Timberlake dominated Thursday's MTV Europe Music Awards, winning best male singer, best pop act and best album for Justified. Christina Aguilera, who hosted the show, was named best female singer, while Beyonce Knowles won best song for "Crazy in Love." Aguilera opened the show wearing a nun's habit, which she quickly removed to reveal shocker! a barely-there top and leather chaps. She's so unpredictable!
