Lady Gaga
Last year, Lady Gaga performed at the Super Bowl, singing the National Anthem. This year she returns as the headliner for the halftime show and she has said that she's been dreaming of this moment since she was just 4 years old. For weeks, Gaga has rehearsing with dancers in a tent that was erected in her backyard. She has also taken advice from her younger sister, who has suggested that Gaga be suspended in air for the big event. We'll have to see if the rumors are true about Gaga performing from the roof of the stadium at tonight's game. For tonight's performance, Gaga tells CBS Sports: I'm going to be taking the spirit of many performers with me on that stage when I go up there. (Getty)
