Merry Ex-mas! Rita Ora wears odd doll-like outfit with thigh-high boots and suspenders as she avoids former flame Calvin Harris at Jingle Ball in New York

Merry Ex-mas! Rita Ora wears odd doll-like outfit with thigh-high boots and suspenders as she avoids former flame Calvin Harris at Jingle Ball in New York, This is what happens when you and your ex are both highly in demand in the music industry.

Rita Ora was in New York at the iconic Hammerstein Ballroom for the Jingle Ball on Friday... along with her ex-boyfriend Calvin Harris.

With the 24-year-old performing three times and Calvin also taking the stage, the pair would have struggled to miss each other.

In true Rita Ora style, the 24-year-old singer had a costume change or two. With not one but three performances, and a backstage interview the R.I.P singer switched things up four times.

Ranging from classic, to costume to urban, the Adidas collaborator finished up the night in a velvet romper suit, with hints of an Alice In Wonderland theme.

From the high necked, Victorian style white shirt, to the dramatic black velvet, the doll-like outfit certainly had a theatrical air to it.

The structured bodice showed off her impressively slim waist as she first teamed the look with sexy suspenders.She showed off her very toned bottom in skin-toned tights and very high thigh-high boots.

Back in August Rita opened up about the split, which Calvin confirmed on Twitter at the time. She told Britain's Glamour magazine: ‘We both work really hard, we're both all over the place.

‘I'm not doing too great but I'm doing better than I thought. I adore him and he's an amazing human being.’ The R.I.P singer also admitted she would never have spoken about their split on Twitter if Calvin, 30, hadn't used the social media site to confirm their romance was over.

She added: ‘Honestly, if Calvin hadn't done it, I wouldn't have. It took me five days to write three sentences. It was massive.’

On Friday night she showed no signs of heartbreak as she switched up her looks and dazzled crowds with her high-energy performances.

For one of her solo trips on stage she swapped her thigh-high heeled boots for black and white flats and added dark opaque tights.

Pulling her hair back into a tight high ponytail, Rita kept her make-up the same through-out the night. Radiant skin was the theme of the night with strong brows, lashes and scarlet red lips.

One other thing that stayed the same throughout the night was a braid down the centre of her parting.
