Выбрать из текста Бритни Спирс главное по английски Britney Spears is one of the world's famous pop princesses [,pnn'seslz]. But how did she become famous?

Britney was born in Kentwood, Louisiana, the USA. The girl was born on 2-nd December 1981. Even when she was very young, she loved music and singing. She sang popular songs at home and at school, and people said, she had a real talent for singing. The first person who asked Britney to sing for other people was her mum. And that was a success.

She studied drama and singing at a school for talented children. When Britney was eleven, she was in television show the "Mickey Mouse Club" and that was a success too. After the "Mickey Mouse Club," Britney went to Kentwood to go to high school'. After high school, Britney started working on her first album "Baby One More Time."

Now she has got a big house in Beverly Hills and a restaurant in New York. She opened it in June 2002.

Britney always says, "Follow your dreams! Don't listen to any one, who says you can't be successful!"
