Seriously, which one is it?
JLS annouce title of fourth album
The boys reveal the name of their upcoming record and release date
JLS' fourth studio album will be called Evolution.
The boys revealed the name on Twitter and posted a message on Soundcloud.
'We've just landed and obviously all you guys know that our album name has been leaked a little bit sooner than we expected, Evolution' said JLS.
'We're very excited about it and this is the album we wanted to make, we wanted to make this for our fans. We didn't go by any kind of guidelines or anything like that, we just made what felt right and we're really excited about it!' concluded the band.
Evolution comes out on November 5.
And if truth be told, they've both got a great set of lungs on them!
