Five Grammy nominations. Four consecutive top 10 singles. Three consecutive #1 songs. A well-received headlining world tour. A meet-and-greet with Queen Elizabeth. A show-stopping appearance on Saturday Night Live. It can't be denied -- Lady Gaga had one incredible year. Usually, stats like these are reserved for the huge one-name acts: Madonna, Britney, Beyonce. But it appears it's time to add one more name to that list: Gaga.
