Beyoncé

Adele dedicated her 2017 Grammy Award for Album of the Year - which she won for '25' - to Beyoncé (who missed out with her record 'Lemonade') and the 'Break My Soul' songstress later described her as the most "humble" person she has ever met in the music business.

She said: "It is so easy to talk to her and be around her. She's funny as hell and her comebacks are legendary. The most beautiful thing about Adele is that she has her priorities straight. She is a gracious woman and the most humble human being I've ever met."
