As you all know, Little Mix's latest album Get Weird was their biggest one (820K WW) yet outselling US big popstars recent efforts like Selena Gomez, Demi Lovato, Fifth Harmony, Meghan Trainor, etc.
They seem to have hype for their new single and album coming out in matter of weeks. Also they're releasing in the end of the year which sales are usually bigger. Will LM4 sell 1M worldwide?
