The Made in Chelsea star took to Instagram on Tuesday (31 March) when she posed for a super-glamorous selfie while revealing her new make-up must-have to her adoring followers.
"Obsessed with @actidermofficial makeup range," Rosie posted. "Love this lipstick in Mauve Mousse!"
Not heard of ActiDerm? Then it's about time you did, because the range has a whole host of skincare, bodycare, nutriceutical supplements and make-up up its sleeve!
Rosie's latest favourite is the Gloss Creme Lipstick in Mauve Mousse, £12.50, actiderm.co.uk which, if this picture is anything to go by, is the perfect shade for pale, English rose complexions like Rosie's.
And coupled with her strong brows, black lashes and contoured cheeks, the reality star really does cut a very fine picture.
For a similar, creamy mauve pout, we also love Maybelline Colour Sensational Lipstick in Magic Mauve, £6.99, superdrug.com.
Apply it with a brush for a long-lasting finish and ditch the liner for a more natural-looking lip.
