Lady Gaga

Prior to launching her music career, Lady Gaga worked as a waitress at a diner after school, where she learned to keep a straight face while serving customers.

The ‘Die With a Smile’ hitmaker later recalled saving up her tips to make her first significant purchase.

She said: “I was so excited because all the girls at Sacred Heart always had their fancy purses, and I always had whatever. My mom and dad were not buying me a $600 purse.”
