Sorry you're just getting a response now! The forums aren't used very frequently here and activity on the Wiki has been a bit slow lately. 

Anyways... To answer your question, unfortunately, other than her social media (which she rarely uses and doesn't even have access to herself), there is no direct way to contact Adele. I've tried to write fan mail to her on several occasions before and have never gotten a response, so unfortunately, I don't really know of a way that you can contact her. 

Sorry about that!
