Before they were stars: Celebrities' past jobs

46 of 77: Before becoming the world famous Lady Gaga, Stephani Germanotta was a waitress at a Greek restaurant, a New York University student and on the MTV reality show 'Boiling Point.'

'I used to be a waitress - I know what it's like to mop the floors,' Lady Gaga said on Howard Stern's Sirius XM radio show on July 18, 2011, adding that she also used to work 'at a music publishing company for nothing.' ( Photo / Facebook.com/ladygaga)
