Rosie has a longstanding relationship with Marks & Spencer, having collaborated with them many times on lingerie collections.
Meanwhile, Rosie is welcoming in the New Year with a brand new makeover. The 27-year-old is renowned for her long blonde locks, however she recently revealed on Instagram that she has had a few inches chopped off.
In the photo, Rosie shows off her model credentials as she poses and unveils the new shoulder-length hairstyle, blow dried and full of volume for an effortlessly glamorous look.

"Ready for 2015 equipped with a fresh new do!" she captioned the image. "Thank you to my favourite brother sister hair duo… @georgenorthwood @sallynorthwood. #ShortHairDontCare #GeorgeNorthwood #SallyNorthwood #BeThereOrHaveBadHair."
Although Rosie's job as a model sees her sporting different hairstyles from sleeked back ponytails to loose old Hollywood-style curls, the Plymouth-born actress has consistently kept her hair at a length tumbling past her shoulders, making her choice of a shorter, layered style all the more drastic.
The British beauty headed home to Devon for Christmas to spend the festive period with her family, no doubt to enjoy some downtime before her hectic work schedule starts up again.
2015 will see Rosie returning to the big screen as she stars in Mad Max: Fury Road, as part of a star-studded cast which includes Charlize Theron, Nicholas Hoult and Tom Hardy.
