Adele playing the 2017 Grammy Awards Ceremony
She'll be playing a song off 25, and it'll be her fourth time performing. Adele is up for basically all the major categories, and it looks like her main competitor this year is Beyonce (unless Sturgill Simpson pulls a dark horse win on Album of the Year).
25, released in 2015, was the highest selling album of that year and of 2016. It surpassed Taylor Swift's 1989 as the highest selling album since... Adele's last album.
