Beyonce

The Grammy winner used to sweep the hair off the floor at her mom Tina's hair salon long before joining Destiny's Child and becoming one of the biggest music stars on the planet in her own right.

She told Essence: “From 6 to 9 years old, I would sing and put on little shows by myself for the women who wanted a hot press and curl and some good conversation. I helped sweep hair off the floor for tips to pay for my season pass to Six Flags. (I still love a good roller-coaster ride.) And when I wasn’t cleaning up the salon, I was watching my mother become my greatest role model.”
