We love the Little Mix girls!
"It's a really long process until you finally get what you think is the final perfume," Jade told us about nailing the perfect scent.
But the girls totally believe that smelling good is important, with Jesy saying: "When you go out on a night out, it's really important that you smell nice, and when you're meeting and greeting people."
Her bandmate, Leigh-Anne, agreed: "Different perfumes remind you of different parts of your life - or different holidays you go on."
The girls revealed to Alex that The X Factor wasn't a great time for their makeup look, with Jesy confiding: "X Factor wasn't our choice, we just got it flung on our face! We didn't want to say anything because we didn't want to be divas."
Leigh-Anne added: "We went from wearing hardly anything - not really knowing anything about makeup - to all of a sudden having a full face every day… but now, we've evolved and we know what suits us and what looks good on our face and makes us look good."
Once you watch the video you'll see that the girls really do LOVE makeup - especially Jade, who the girls unanimously agreed was the best with her application skills - and has been known for doing the girls makeup when their resident MUA, Adam Burrell, is MIA.
The Little Mix girls also know it's not about looking the same. Jesy said: "From the very beginning, we've always gone with what we feel comfortable with, and we've also got different colour skin tones, and different colour hair… so what may suit me, may never suit Perrie. We're very individual and we like to keep it that way, and in a way that's what brings us together that we're all different, I think it's cool."
The girls have been with their makeup artist Adam Burrell since day they graduated from The X Factor, and they've learnt a lot from his expertise; from contouring to choosing the perfect set of false lashes, right down to the correct brushes to use.
