Amy Winehouse has defended her performance at Thursday's MTV European Music Awards - citing exhaustion for her bizarre behavior. The troubled star - who won the Artist's Choice award - mumbled through a performance of hit "Back To Black" at the ceremony in Munich, Germany, and appeared to have forgotten the song's lyrics. But Winehouse insists her busy schedule was to blame for her lackluster performance, after beginning a 27-date European tour last month. She also admits she only agreed to appear at the EMAs to please her family. Winehouse says, "I can't really be bothered going to perform but my family love these kinds of awards shows and watching me, so I'm doing it for them really. I'm knackered after my own gigs in Europe and was back in London chilling out when I got the call asking me to MTV. My family are so important to me that I agreed to do it for them."
