Singing and dancing in stilettos since the age of nine, Beyoncé Knowles has been well prepared for superstardom. The Texan triple-threat began as lead singer of the Grammy-winning Destiny’s Child, one of the biggest female groups of all time (40 million albums sold worldwide). Her 2003 solo debut, Dangerously In Love, featured her then-boyfriend Jay-Z on “Crazy In Love.” Beyoncé has since released four more solo albums, with hits like “Irreplaceable” and “Single Ladies (Put A Ring On It)”; collaborated with the likes of Shakira and Lady Gaga; starred in films such as Dreamgirls and Cadillac Records; and sung the Etta James classic “At Last” while President Barack Obama and First Lady Michelle Obama danced following his 2008 inauguration. In addition to running the fashion label House of Deréon with her mother Tina, Beyoncé (a.k.a. Sasha Fierce) married rap mogul Jay-Z and on January 7, 2012 they welcomed their first child, Blue Ivy Carter. Bey gave fans a shock when she unexpectedly dropped her self-titled LP in December 2013. In 2014, she was crowned the highest earning Black musician in history. Most recently, Beyonce released her visual album, LEMONADE, and will embark on her "Formation World Tour."
