They both pitched up at Topshop in Oxford Circus with matching leather looks and were pretty inseparable.
She wore her blonde locks swept to one side and for the beauty was rocking a bright red lip and had some seriously smokey eye action going on.
Miss Green, daughter to Topshop owner Sir Philip Green, was also feeling a bit rock chic in a pair of black leather dungarees worn with a monochrome top underneath.
She shared a selfie of the pair on Instagram and in the caption said: "Reunited at last @ritaora !! Celebrating CJG Spring Summer launch!!! I have missed this girl!!! Love you xxx"
But the fun didn't stop there, because Rita and Chloe headed out to party at London's Chakana night club.
We're not quite sure why (and we're hoping it was some sort of fancy dress party), but the 'RIP' singer left the club wearing a pvc catsuit with matching ears. Chloe was still wearing her dungarees combined with a black jacket and wooly hat with some beads for extra detail.
