This is one Hollywood actress who truly began her professional modeling career at a tender age of 11 months! Well, Brooke Shields was born to be an actor. Her bedazzling looks earned her an early entry into Hollywood, making her a child star through a lead role in Pretty Baby. Brooke also moved on to become a teenage heartthrob with her roles in movies like Endless Love and The Blue Lagoon. Although, she later on moved to working in television, but we all still let out a sigh every time we watch Brooke Shields in The Blue Lagoon!
