Country singer Taylor Swift has admitted that she encounters Amnesia and loses her mind after winning an award. The 'Love Story' hitmaker,who has won a string of honours,including four Grammys always plans acceptance speeches but gets so overcome with emotion she can never remember what she wanted to say,Contactmusic reported. "I've been lucky enough to win a couple of awards this year and there's always that moment when I'm walking back stage and I have to ask someone what I said. I always have an idea who I want to thank if I win but when I get out there I totally lose it and I'm like,'I can't believe this!' I get completely emotional," Swift said. The 20-year-old singer insists when after exiting the stage she has no memoir of her speech. "I end up thanking my dad,mom,brother,pets. I have no control of what is coming out of my mouth. I forget everything I've said by the time I walk off the stage," Swift said.
