One of the most shocking aspects of Sia’s rise to fame was that nobody knew what she looked like. The Australian pop star famously hid her face when her career exploded. But this came with a cost because Sia had a serious alcohol problem that threatened her life.
Sia said that she was suicidal and credited actress Kathy Griffin with saving her life. Griffin reportedly convinced Sia to seek help and she went to rehab. In the end, she became sober and ended her toxic relationship with alcohol. She was lucky because many people don’t get a second chance (via Variety).
