Kelly Clarkson reaches a music milestone.

Breakaway has sold 5.5 million copies worldwide and generated four No. 1 singles. Quite impressive for the little girl from Texas with the big voice.

Kelly is only one of only four artists in Sound Scan history to debut in the Top 20 and stay there for a year straight, and is the first artist in over 5 years to accomplish this.

The album's first four singles, Breakaway, Since U Been Gone, Behind These Hazel Eyes and Because of You have all reached No. 1 in America. . . . . .Full Story
