So the songstress made us love her even more when she revealed her favourite beauty brand is actually super-cheap!
Speaking exclusively to Reveal at the Virgin Media Louder Lounge at V Festival in Chelmsford on Saturday (17 August), Mollie gushed about the bargain range she can't get enough of.
"I'm loving Maybelline make-up right now! Both my red lipstick and black eyeliner are by Maybelline," revealed Mollie.
"I also like their foundations, but my favourite has to be MAC Face and Body Foundation, £21.50, I wear it all the time. I like to put it over my eyelids too before I apply eyeliner."
Want in on the action?
We love Maybelline Eye Studio Lasting Drama Gel Liner in Black, £7.99, which performs just as well as its more expensive counterparts. It's also a favourite of celeb make-up artist Lisa Eldridge.
Make like Mols and pair with a pop of colour on your lips. Try Maybelline Baby Lips Lip Balm, £2.99 each, which have just landed on UK shores after causing a stir in the US. We'll take one in each flavour, please!
