Britney Spears' famous fans and friends have her back. The 39-year-old singer spoke out for the first time at her conservatorship hearing on Wednesday, and stars including Lena Dunham, Keke Palmer, Cara Delevingne and Mariah Carey took to social media to show their support. Spears, who has been under the legal conservatorship for 13 years, joined the Los Angeles court hearing remotely amid COVID-19 protocols, and did not hold back in her account of her experiences.
