Before this lil' star with his sword was an international star, he was just throwin' on his tricorn, fighting his way to be a musician and growing up in England ... Arr you prepared to guess this matey?
Aside from his superior singing skills, he's written songs for some of music's hottest stars like The Weeknd, Taylor Swift and Justin Bieber -- whom he's also collab'd with vocally, but perhaps you don't care.
One of his top songs is a popular and perfect wedding song.
He may know the "shape of you," but can you guess who this a-list celeb is?
