The announcement was made Wednesday just prior to her wrapping the overseas portion of her Speak Now World Tour 2011 with a sold-out show at London's O2 Arena.

Big Machine Records and Universal Music International executives presented the 21-year-old singer with a plaque commemorating the achievement at a special backstage event at the O2, the record label said.

Her 20 million plus albums sold include her CDs "Fearless," "Speak Now," "The Taylor Swift Holiday Collection" and "Beautiful Eyes."

Swift recently added 16 dates to the North American portion of her tour, which kicks off May 27 with two sold-out shows at Omaha's Qwest Center and now wraps with two shows at New York's Madison Square Garden just before Thanksgiving.

In total, she will have headlined 97 stadium and arena shows around the world this year.
