Don’t panic! Leona Lewis hasn’t totally lost the fashion plot here: Perez Hilton’s 32nd birthday party did have a Carn-Evil theme (make of that what you will), and Leona is simply dressing the part. We think Katy Perry came in fancy dress too, although it’s sometimes hard to tell with Katy, hmm?
This looks like it was a pretty fun night, fashion wise. Take a look at the gallery below for more outfit shots!
