“Harlequin” will be released on Sept. 27 and feature 13 songs. In the lead up to the announcement, Gaga teased fans with posts to Instagram “I’m ready for my interview,” read one post, while another said: “Don’t tell me what to wear.” A third post, which was accompanied by the lone plucking of an acoustic guitar, read: “No duct tape. No mission.” She also teased the album earlier this week with billboards including the number “6.5,” which presumably means that she does not consider this a full Lady Gaga studio album, unlike the forthcoming one that has been written in shorthand “LG7.”
