Rita Ora performs new single Anywhere on The X Factor ITV

She said: "Woke up with a smile this morning! Thank you ❤️ #anywhere".

Her controversial performance on The X Factor last week no doubt garnered her new single some attention as her skimpy outfit caused a social media debate.

Ora sported a pair of black knickers with a black top, hoodie and boots with her hair in tight curls for a Flashdance theme. But many viewers took to social media to express the inappropriateness of her outfit.

One person claimed: "Has she forgotten to put on her pants?" while someone else said: "I thought Rita Ora was terrible on #XFactor . Her outfit was totally inappropriate for Saturday Night TV w/many kids watching! Awful outfit!"

Many of the singer's fans were quick to stick up for the Hot Right Now hitmaker, with one person tweeting: "The intense slut shaming of Rita Ora and her outfit is ridiculous. Y'all acting like u don't see things like that in music vids all the time".
