Kesha
Who: Kesha Rose Sebert is an American singer, songwriter, and actress. 

Why she's fearless: While embroiled in a vicious and controversial legal battle with her former producer Dr. Luke since 2013, Kesha was unable to release new music of her own. Even so, she bravely came forward to accuse him of physical, sexual and emotional abuse, despite the ramifications this had on her own musical career.

Happily, she's since returned to music, releasing her third studio album, Rainbow, in 2017 — and inspiring victims of abuse everywhere to tell their stories.

Our musical picks: "Praying," "Woman," "We R Who We R"
