Adele's got Kesha's back ... and she just used a huge public platform to let the world know it.
Adele was accepting an award for Best Female Solo Artist at The Brit Awards -- which are going down Wednesday night in London. She went through the usual thank yous ... shouting out her management and record label for embracing the fact she's a woman.
And then Adele brought up Kesha's legal battle with Dr. Luke. It was a remarkable endorsement from the most popular artist in the world -- especially coming one day after the videotaped deposition ... where Kesha said Luke did NOT rape or drug her.
No surprise ... the crowd went nuts for Adele's show of support.
