'So Stupid' will be released alongside their forthcoming single 'My Heart Takes Over', which is out on November 13.
Lyrics to 'So Stupid' include: "I should feel like cursing out your name/ I should feel so crazy I'm insane/ I should feel like crying 'til I die/ I should feel like breaking down inside/ But all I feel is so stupid."
'My Heart Takes Over' marks the third cut from the group's upcoming album On Your Radar, which follows on November 21.
The band recently told Digital Spy that their new album had "some real tearjerkers" on it.
