So it comes as no surprise that The Saturdays singer has been snapped up by Maybelline to be their new brand ambassador.
Gorgeous Mollie channels her inner rock chick in the campaign image, sporting a leather biker jacket and a messy scraped-back 'do.
She switched her trademark black liner for a shimmery metallic shade, contouring her cheeks with a sweep of bronzer.
To finish, she slicked her pout with a loud-and-proud vivid pink, courtesy of Maybelline Colour Sensational Lipstick in Fuchsia Flash, £7.19.
If you fancy stopping by, Mollie will be in the Maybelline 'Make It Up' lounge tomorrow morning (21 September) from 9am until 2pm - and you can get your mitts on a limited edition lippy signed by the starlet!
Talking about her new venture, Mollie said: "Maybelline was the first make-up brand I discovered and I've loved using it ever since, so I am thrilled to be their ambassador at Vodafone London Fashion Weekend."
And at Virgin Media's V Festival last month, Mollie spoke exclusively to Reveal about her love for the bargain cosmetic line.
"I'm loving Maybelline make-up right now! Both my red lipstick and black eyeliner are by Maybelline," she gushed.
"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."
Cheers for the tip, Mols!
