Rita Ora Leads The Fashion Stakes At Jingle Bell Ball 2012

The pop sensation tweeted a picture of her jacket ahead of her performance at London's O2 Arena.

Rita Ora is ready to 'Party' at the Capital Jingle Bell Ball this evening at London's O2 Arena, changing in and out of a stunning yellow before her performance on stage.

She tweeted a picture of her jacket and slicked back blonde hair ahead of this evening's performance (9th December).

The 'R.I.P.' singer made an entrance on the red carpet, giving up her jacket and changing into a long cutaway yellow dress, revealing her tattoos for the cameras.

Back on stage, Rita changed back into something slightly more casual for her performance, matching her 'Whatever' jacket with red lipstick, white high-waisted trousers and trainers.
