Who? Rita Ora
What? Disappointingly, Ora toned it right down for Halloween this year. The only give away was a pair of cute cat ears that peeped out from her blonde curls. Perhaps she didn't want to out-spook Mr David Letterman? Either way, her outfit was far from boring. She left his show in a floral print jacket paired with bright green trousers and wedge heels.
Where? Ora is was all smiles outside the Ed Sullivan Theatre for The Late Show with David Letterman in New York.
Verdict? Whilst we still love her signature red lipstick, we can't help but wish we'd seen more of a #trickORAtreat.
