And we know exactly what lipstick was used to create their perfect, Hollywood pouts. Interested? Thought so...
The band, which includes Jade Thirlwall, Jesy Nelson, Leigh-Anne Pinnock and Perrie Edwards (as if you needed reminding!) are currently touring down under and gave a stunning performance of their latest single, 'Love Me Like You' on Tuesday night (13 October) when they were the guest act on the Australian version of the show that made them famous.
We've been keeping a keen eye on their style while on tour and they ladies have not disappointed us with their super-curly hair, chocolate-brown lips and gorgeously glam make-up.
For Monday's performance it was all about movie-star glamour, as their make-up artist and BFF Adam Burrell gave the girls classic, sexy make-up that was to... die... for.
"Old Hollywood faces for #littlemix," Adam Instagrammed, along with snaps of Jade, Perrie and most importantly, the loot he used to create their looks.
Thanks Adam, we can always rely on you to deliver the goods!
In amongst the MAC Cosmetics, Bobbi Brown and Charlotte Tilbury goodies, we spy the tool he must have used to create those must-have, perfectly-shaped red lips...
The product in question is Barry M Matte Me Up Lip Crayon in Make A Statement, £4.99, barrym.com, a creamy, matte pencil you apply all over your lips for long-lasting colour.
We watched Little Mix sing on Tuesday night's show (below) and we have to admit, it was perfectly clear that each of their pouts kept up the pace of a live performance.
Cue: round of applause for Barry M!
ps: We also love Nars Velvet Matte Lip Pencil in Dragon Girl, £19, narscosmetics.co.uk for a similar look, albeit without the bargain price tag!
