Taylor Swift, who just wrapped the overseas leg of her Speak Now Tour, arrived in Vegas for the 2011 ACM Awards with a little jetlag, but that didn't keep her from giving an honest and sincere acceptance speech when she took home the night's top honors: Entertainer of the Year.

"This is the first time that I've ever won this, and I'm just losing my mind!" a shocked Swift said as she clutched her fan-voted trophy. "The fact that this is from the fans makes it so beautiful. Thank you so much to the fans and anyone who voted ... thank you for this wonderful 'Welcome Home' gift, and thanks for not forgetting about me. You are the best thing that has ever happened to me, ever! Thank you so much."

Swift will continue the U.S. and Canada portion of her Speak Now tour in May. Frankie Ballard will open the tour's first leg. Click here for a complete list of dates where the new reigning ACM Entertainer of the Year will be performing.
