Barbra Streisand, who turns 75 today (April 24), is the best-selling female recording artist in history. The superstar has sold 68.5 million albums in the U.S. over the years — 4 million more than her nearest rival, Madonna. (You could say the Funny Girl tops the Material Girl.) Streisand is the leader among female artists for most gold albums (51) and platinum albums (30).
