In 2008, she was just some lady.
Barely anyone knew the name Gaga when she first showed up in Charlotte as the opening act for New Kids on the Block's reunion tour that October.
Today, on the eve of her sold-out Charlotte concert (8p.m. Saturday at Time Warner Cable Arena), Lady Gaga stands among the world's most influential musicians. Despite only two albums to her credit, her "The Fame" and "The Fame Monster" have sold more than 15 million copies, and sales of her singles are at 51 million and rising. Fast.
The 24-year-old singer, born Stefani Joanne Angelina Germanotta, also has been a tabloid favorite, a controversy magnet who always seems to be making headlines for bizarre reasons.
