Release Derulo was originally set to release the full length album of Tattoos both in the United States and Internationally on September 24, 2013, however after a last-minute shift in strategy between Derulo and his label. "Tattoos" was released as a five track EP including the first three singles plus two extra songs, with the full length album to follow shortly after the release of a third US single. Derulo had confirmed that he was working on new material to be released specifically for the U.S. version of the album. Explaining the last-minute shift in strategy, Derulo said, "I know the fans they wanted something here and I wanted to give the fans at least something other than just the single. So I'm doing the EP and then the album will come out shortly after that."
