Lady Gaga's fourth album will be called ARTPOP, with the singer making the announcement via a new tattoo. Gaga is currently working on the follow-up to her second album Born This Way, which has gone multi-platinum around the world since its release in May last year. Gaga took to Twitter to tease details of the new release, posting a picture of herself with the caption "new ink new album." The new tat sees the word ARTPOP written in capital letters on the inside of Gaga's arm. Gaga then posted an image featuring the words "we could/we could/belong together. ARTPOP."
