Miley Cyrus, who stars on Disney Channel’s highly popular series Hannah Montana, has made musical history by becoming the youngest artist to have two number one albums in less than a year in the United States. The 14-year-old singer/actress, whose dad/co-star is country singer/actor Billy Ray Cyrus, shot to the top of the American charts last week after selling 326,000 copies of her new double album Hannah Montana 2/Meet Miley Cyrus. Her first CD, Hannah Montana, went straight to the top of the U.S. charts in October 2006.
