This time? She's wowed us with something totally different in the new issue of Elle UK... a platinum blonde wig!
The stylish supermodel posted a snap of her temporary 'do on Instagram this week (2 September) complete with a full fringe and shoulder-length cut.
Her show-stopping look was for her cover shoot for this month's issue of Elle and came courtesy of top London-based hairdresser, George Northwood.
In the shoot, she can be seen wearing vampy dark lips and creating a variety of tricky-looking poses!
Seriously hot, right?
While we're not sure we'll be showcasing a similar bouffant anytime soon, Rosie's eye make-up was one look we are dying to recreate!
She showed off one of the hottest beauty of the moment - statement winged eyeliner.
Master it now and you'll be rocking it 'til next summer! Here's how:
1. Black liquid liners come in various forms from felt tip pen-esque like Sleek Flick It Eyeliner in Dazzling Black, £5.99, to a thinner brush-style like 2True Effortless Eyeliner in Black, £1.99. Have a play around to discover which you find easiest. Everyone's different!
2. Once you've selected your liner, place your elbow on a steady surface and trace your upper lash line. Work in small sections from the outer end of your eye inwards.
3. Don't do one eye all in one go - this makes it really tricky to get them to match! Instead alternate between sections on each eye.
4. Next draw your flick, making it line up with the end of your eyebrow for the most flattering effect.
5. Then draw a line from your wing back into the inner corner of your eye, again working in easy-to-manage sections. Carefully fill it in for a strong winged effect.
6. Use the same liner to trace your lower lash line too but don't take it right into the inner corners.
7. Take a white pencil liner and apply it to the inner corners and along your waterline (that's the bit closest to your eye). This looks super-edgy and has a brightening effect too.
8. Finish with lashings of mascara and a mega pout!
TOP TIP: Try tracing out your winged effect first using a light-coloured eye pencil to make sure it's perfect!
