Taylor Swift is gearing up to kick off her 2011 Speak Now Tour, but not until the singer opens her dress rehearsal performance up to the public as part of her 'Speak Now ... Help Now' event, benefiting those affected by the devastating tornadoes that ripped through the south in April.

Since announcing the special performance scheduled for Saturday, May 21 at Nashville's Bridgestone Arena, Swift has decided to give everyone at home the chance to be part of the special night, as part of the show will be streamed live online.

"I'll be streaming 2 of the songs from the Speak Now/Help Now rehearsal performance worldwide- Saturday at 9pm central on taylorswift.com,”  Swift tweeted Thursday afternoon.

The stream will give fans all around the world a first look at Swift's new stage and her show for the North American leg of the Speak Now World Tour.

All the proceeds raised from ticket sales to the special dress rehearsal event will go directly to help the tornado victims via the Speak Now ... Help Now Fund established through the Community Foundation of Middle Tennessee. Additional information on how to donate to help tornado victims will be posted during the stream Saturday night.

'Speak Now … Help Now' is the final dress rehearsal for the tour which is set to kick off May 27 in Omaha, Neb. with hot country newcomer Frankie Ballard opening the show.
