The British pop star was pictured out and about in the Big Apple yesterday (17 October) and no doubt turned quite a few heads with her latest colourful locks.
Mixing up her trademark bleach blonde, Rita has added splashes of blue, orange and pink to her hair, which actually appear to be in keeping with the current hairstyle trend of colourful dip dyes.
But somehow we don't think she will be able to go incognito with that 'do now!
In contrast to her striking head of hair, Rita kept her outfit simple with a pair of light blue dungarees, a plain white T-shirt and some white creepers.
She accessorised with a gold cuff around her wrist and a pair of gold earrings - although they are pretty tricky to spot among those dyed tresses - and she carried a large blue and red bag for all of her essentials.
The award-winning songstress has been over in the States for the last few days and as well as catching up with boyfriend Calvin Harris on a date in LA, she has begun work on her second studio album too.
Rita posted a snap of herself in the studio on Wednesday (16 October) with her team and wrote: "Here we go. Team starts now! #Album2 #AsAlways #family #itscoming #arrgghhhhhh @calvinharris we miss you!"
This new album has alot to live up to, since Rita's debut project, Ora, reached number one in the UK charts.
