     Stella was born on September 13, 1971 in London, England. She was the daughter of Paul

McCartney, a member of the world-famous band “the Beatles.” Though she was born famous,

her parents wanted her to live a normal and independent life. She went to state school and earned

pocket money on her own. She didn’t get the kind of allowance other kids of her age might have.

When she wanted pocket money, she had to clean dishes at a restaurant near her home.

     Though Stella had the look to become a model, she was most interested in becoming a fashion

designer. At the age of twelve, she made her first jacket. Three years later, she started working on

her first fashion design collection. When she attended college, some students called her “Daddy’s

Girl.” But when her graduation fashion show came out, she made them shut up.

     Later, she worked for some famous brands and achieved great success. In 2001, she started her

own brand and began to have some famous customers like Liv Tyler. Now she is a world-famous

fashion designer.
