Tickets for the first ten shows of Taylor Swift's Speak Now tour went on sale on December 4, and sold out within minutes, prompting the superstar to add three new dates to her concert schedule. Taylor will now play a second date at Gillette Stadium in Foxboro, Mass., on June 26, and two more shows at the Staples Center in Los Angeles, August 27 and 28. Tickets for the Gillette Stadium show will go on sale December 10, and tickets for the Staples Center gig go on sale December 11.

The reigning concert queen is scheduled to perform 90 dates in 19 countries as part of the Speak Now tour, which kicks off February 9 in Singapore. Taylor, who celebrates her 21st birthday next week, enjoys her globetrotting lifestyle. "World travel is something I really love," she notes. "It's something I've always wanted to do, and now I get to do it and sing music at the same time."

Taylor's tour will take her to Japan, Hong Kong, Germany and the U.K. NeedtoBreathe will join as the opening act for her U.S. dates.
