21. It's the number most often associated with Adele, due to her best-selling album, one of the most popular in the history of the universe.
But let's all focus on 24 today instead, shall we? That's because it's the new age of this incredible artist. That's right... it's her birthday!
The singer's 2011 was easily one of the best years ever for a musician, and she kicked off her 2012 in impressive fashion, as well, returning from throat surgery to simply dominate the Grammys. Just watch this rendition of "Rolling in the Deep." Wow.
Adele is now one of the Most Influential People in the World.
And she's only 24! Just barely, to boot! Send in your birthday wishes now.
