American pop singer Beyoncé turned 36 years old Monday. Throughout her career, she has sold hit records and starred in movies and television ads, but how much is the entertainment star worth?

Beyoncé has an estimated net worth of $450 million, according to Celebrity Net Worth. She had her first taste of stardom when she appeared on the 1990s television show "Star Search" as a member of the performance group, "Girl's Tyme."

Columbia Records signed the group to a record deal in 1997 under their new name, "Destiny’s Child." They went on to see massive success and released seven studio albums. Five of the group’s albums went certified platinum. They sold over 50 million records worldwide.

She became one of the world's most best-selling artists and her most recent album, "Lemonade," sold over 2.5 million copies worldwide. She also started acting with leading roles in movies including Cadillac Records, Obsessed, Austin Powers and Dreamgirls.

The Texas-born singer inked her first endorsement deal with beverage company Pepsi in 2002. She signed subsequent endorsement deals with American Express, Samsung L'Oreal, Ford and DirectTV. Beyoncé launched several fragrances and signed a three-year deal to develop a signature fragrance for beauty brand Coty.

Beyoncé married rapper and entrepreneur Jay-Z in 2008 and together their net worth is $1.35 billion, according to Celebrity Net Worth. Jay-Z, whose real name is Shawn Carter, has a net worth of $900 million. Their marriage landed them on the ten richest celebrity couples in the world list, according to Celebrity Net Worth.
