The Chelsea girl uploaded a snap to Instagram today (25 February) and looked super glamorous.
Wearing a classic LBD, Rosie had slicked back her locks in a similar style to Alexa Chung and Taylor Swift at last night's Elle Style Awards, which showed off her perfectly made up face.
Oozing elegance, she added subtle contouring along her cheekbones, which she paired with groomed brows and a slick of mascara – proof that keeping the rest of your make-up low key is fab when you're sporting statement lips.
Rosie's pout was painted a vibrant orange-red hue courtesy of NARS Velvet Matte Lip Pencil, (£19), in shade Red Square.
These super easy-to-use pencils are perfect for those who are less experienced with wearing a bold lippy.
The pencil-application means you can precisely draw your smackers' natural shape. Start off by carefully outlining your pout with the pencil before filling in the middle to get an even, high-pigmented colour.
Its matte finish means this formula can be a little drying on lips, so make sure you load up the lip balm beforehand.
Everyone from Jasmin Walia to Lauren Pope loves these nifty lip products.
For a cheaper version, we love NYX Cosmetics Jumbo Lip Pencil, (£5), a bargain buy that has a creamy, long-lasting formula and bold colour.
Or, if you don't fancy a pencil, why not try Bourjois Rouge Edition Velvet Lipstick, (£8.99)? Its applicator makes colouring your smackers super simple and leaves your lips with a soft, velvety finish. We really like the statement Personne Ne Rouge shade, which Laura Whitmore is a fan of, too!
Add an LBD and tonnes of mascara, and you're good to go!
