Barbie's one of the most famous women in the world and this year she's celebrating her 50th birthday. We've been checking out some of her looks over the years.
Meet Barbara Millicent Roberts. Barbie made her debut in a TV ad back in 1959, when buying one of the dolls would have cost just $3 - that's about £1.50!
About 350,000 Barbie dolls were sold in the first year. These days she's available in 150 different countries and roughly three of her dolls are sold every second!
Barbie's year of 50th birthday celebrations are kicking off with a huge display of her various looks over the years at a huge Toy Fair in Germany.
She's had more than 100 styles over the past five decades, including everything from astronaut Barbie in 1963 to this All That Glitters Barbie from the Diva Barbie range of 2002.
Ken became Barbie's boyfriend in 1961, but they split up on Valentines Day 2004. The Ken doll then had a huge makeover as toy makers Mattel say he's desperate to get Barbie back.
Despite being with Ken for 43 years, Barbie has never been married. Apparently she just likes modelling wedding gowns for her designer friends!
As well as being a model, Barbie's had a staggering 107 other careers, including Olympic gymnast, vet, scuba diver, doctor and even a rap star! No wonder she needs a rest!
She's not just a career girl though. Barbie's a big animal lover too and has had 50 pets over the years, including dogs, horses, cats, a lion club, a panda, a giraffe and a zebra!
