Jessica Anne Newham, known professionally as Betty Who, is an Australian singer, songwriter, and performer whose vibrant pop anthems and powerful vocal delivery have carved out a distinctive space in the modern music landscape. Born on 5 October 1991, she first captured attention with her independently released debut single, "Somebody Loves You," in 2012, a euphoric burst of synth-driven pop that immediately showcased her knack for crafting infectious, emotionally resonant hooks. The success of that track, along with her debut extended play, The Movement, in 2013, generated significant industry buzz, leading to a signing with RCA Records. Her full-length debut, Take Me When You Go, arrived in 2014, cementing her reputation as a rising star with a keen sense of melody and a magnetic stage presence.

Who achieved her most significant commercial breakthrough with her second studio album, The Valley, released in 2017. The record featured her cover of "I Love You Always Forever," originally by Donna Lewis, which became a global hit. The song peaked inside the top ten on the Australian charts and reached the number one spot on the Billboard Dance Club Songs chart in the United States, introducing her to a much wider audience and solidifying her status as a dance-pop force. The album itself showcased a more mature and cohesive sound, with Who exploring themes of love, identity, and self-acceptance, further endearing her to a dedicated fanbase who connected deeply with her unapologetic authenticity, particularly within the LGBTQ+ community.

Beyond her music career, Who has demonstrated remarkable versatility as a performer. In a stunning crossover into the theatrical world, she made her Broadway debut in the acclaimed musical Hadestown at the Walter Kerr Theater on 5 September 2023, taking on the role of Persephone. Her portrayal of the goddess of spring ran until 4 February 2024, earning praise for bringing her dynamic energy and vocal prowess to the Tony Award-winning production. This foray into theater highlighted her range as an artist, proving that her talents extend far beyond the recording studio. In 2024, she also lent her voice to the children's television series Yo Gabba Gabbaland, playing the character of the Wind and performing the song "I Am the Wind," demonstrating her appeal across generations and genres. With a career that continues to evolve, Betty Who remains a compelling and multifaceted figure, seamlessly bridging the worlds of pop music, dance culture, and Broadway theater.
