One is not enough? Rita Ora switches up her style three times as she leads the British glamour at Jingle Ball

 

Rita Ora is famous for mixing and matching up her style.

The singer was so excited about performing at the KIIS FM 2014 Jingle Ball in Los Angeles on Friday, that she made various outfit changes.

Prior to her huge performance, Rita was spotted making her way into the Staples Center wearing a green elf hat and giant pointed ears.

In the Christmas spirit: Rita Ora arrived at the KIIS FM Jingle Ball in Los Angeles on Friday wearing elf ears and a hat

She was seen stepping out of her car carrying the costume, but waited until she was inside to put it on and surprise everyone.

Rita also wore a white sequined dress printed with motifs of craft supplies, chunky dove grey suede boots with pink buckles, an orange backwards baseball cap and funky sunglasses.

By the time the 24-year-old arrived on the red carpet however, her outfit was considerably less festive.

Quick change: The singer was going for a much racier look when she arrived on the red carpet

The thigh's the limit: Rita wore a tiny black and white mini-skirt with a gold panel split up the front, and paired it with a yellow and black jumper

British invasion: The 24-year-old was seen posing with Sam Smith on the red carpet, and showed off her caged heels

Hold me tight: The close pals embraced on the red carpet

Rita was clad in a black and white skirt with metallic gold panel, and a very revealing slit all the way up one thigh.

The sexy garment fit well with the R.I.P hit-maker's yellow jumper with black print, which read 'Suburbia Gladiator' on the back, and her caged black heels that were sky high.

Rita has been sporting flowing blonde locks recently, but showed off a new bob with blunt fringe, which appears to be a wig, and completed her look with lots of red lipstick.

Another outfit change: When it came time to perform, Rita wore a puffy dress in mustard, with white sides

She wouldn't be without it: Rita finished off her look with her trademark red lipstick

Having a Jingle Ball: The star looked like she was enjoying herself on stage

The British beauty performed a set on her own, and later hit the stage with Iggy Azalea to perform their collaborative hit Black Widow.

Rita changed once again for the performance - and was seen in a puffy mustard dress with black strips and white sides, along with white trainers. 

Making it easier to move around: Rita changed out of her heels and into white trainers for her performance

Joining forces: Rita returned to the stage later in the evening to perform Black Widow with Iggy Azalea

Flashing the flesh: The star wore another racy look in the form of black leather shorts and a navy crop top

In their element: The two ladies rocked the stage with their dance moves

Unique style: The blonde arrived for rehearsals in a sequined frock and chunky boots, carrying her elf ears

When she returned with Iggy, she was clad in a pair of very skimpy leather shorts and a navy crop top with studded neckline.

Rita jetted into Los Angeles from London the previous day before the big event, which also saw performances from Taylor Swift, Ariana Grande and Sam Smith.

And the star took the time to pose up with Sam on the red carpet and Ed Sheeran backstage, before they got ready to head on stage. 

Let's celebrate: Rita then ran into another Brit in the form of Ed Sheeran, who was having a drink backstage

Hard to miss: Jessie J showed off her taut tum in a white one-piece swimsuit
