Adele's support is a significant move, as she is represented in the U.S. by Columbia Records, which is owned by Sony Music, making her one of the few high profile artists on the Sony roster to speak out. (The #FreeKesha movement received a groundswell of support after a judge refused to release the singer from her contract with the record label.) Kelly Clarkson, repped by Sony flagship, RCA Records, has also tweeted a message seemingly in support of Kesha.
Adele, who killed it on the carpet in a flowing red Giambattista Valli dress, also took the opportunity during her acceptance speech to talk about "embracing the fact that I'm a woman, and being encouraged by it."
Meanwhile, Kesha has posted thanks to her fans on social media, and wrote a powerful letter on Facebook Wednesday, writing, "I just want to say that if you have been abused, please don't be afraid to speak out."
The singer has alleged that music producer Dr. Luke (real name: Lukasz Gottwald), 42, drugged and raped her over a decade ago and consistently abused her physically and emotionally. Dr. Luke has denied any wrongdoing, and on Monday, his attorney released a statement to ET calling the singer's claims "outright lies."
