Taylor Swift 'lets it go' in Tampa

Taylor Swift wrapped up the United States leg of her 1989 Tour in Tampa in front of a sold-out crowd Saturday night.

The pop star performed a nearly two-hour set, performing a duet of Frozen's "Let it Go" at one point with Idina Menzel.

Raymond James Stadium sold out for the Halloween night show, with more than 50,000 fans packing the stadium. Stadium officials said the Tampa Sports Authority stood to earn $350,000 from the concert.

FOX 13 learned that 10-year-old leukemia patient Marissa Peddie had her dream to meet Swift come true. An anonymous donor offered up the meet-and-greet passes.

The Children's Dream Fund, who set Marissa and her family up with tickets to the concert, says Marissa sang a song for Swift and the pop start complimented Peddie on her voice.

Swift will head to Asia to continue her tour.
