Sure, there's a ton of starlets out there getting attention for kissing girls and having girl-crushes, but for this year's Celebrate Bisexuality Day, we're tipping our hats to a handful of iconic, artistic women who weren't too scared to keep their options open.

Billie Holiday (1915–1959)
Philly native Lady Day was one of the most influential jazz singers of all time. After a difficult early life, she was discovered in a Harlem jazz club at 18 and started recording tracks with producer John Hammond. She eventually recorded hits that resonate with her period (1930s–1950s) like "God Bless the Child" and "T'ain't Nobody's Business If I Do." Ahead of her time, Holiday was relatively open about her bisexuality, and she was often linked with actress Tallulah Bankhead, who dismissed the rumors. She died of complications from substance abuse in 1959.

Listen to her sing "Good Morning Heartache."
