The singer's first disc + was released in North America early this morning (June 12) and quickly climbed to the top of the list, fending off competition from Usher's new album Looking 4 Myself.
"Oh my word!! My album is -#1 on USA iTunes!,!,!! so happy right now," Sheeran tweeted. "And Canada!,!,!, Getting emotional right now, gonna eat some nachos."
+ reached number one on the UK chart upon its release last September and has since been certified quadruple platinum after selling over 1.2 million copies.
Meanwhile, Sheeran recently released a video of himself and Taylor Swift duetting on an acoustic rendition of his single 'Lego House'.
The pair have been working on tracks together in the studio for Swift's next effort.
