Given a reference text about Britney Spears, tell me when they were born and why they are famous.

Context:
Britney Jean Spears (born December 2, 1981) is an American singer, actress, and dancer. Often referred to as the "Princess of Pop", she is credited with influencing the revival of teen pop during the late 1990s and early 2000s. After appearing in stage productions and television series, Spears signed with Jive Records in 1997 at age fifteen. Her first two studio albums, ...Baby One More Time (1999) and Oops!... I Did It Again (2000), are among the best-selling albums of all time and made Spears the best-selling teenage artist of all time. With first-week sales of over 1.3 million copies, Oops!... I Did It Again held the record for the fastest-selling album by a female artist in the United States for fifteen years. Spears adopted a more mature and provocative style for her albums Britney (2001) and In the Zone (2003), and starred in the 2002 film Crossroads.<|im_end|>
