Fashion Police co-host Kelly Osbourne and Pharrell Williams are "working on something" together.
Taking to her blog, Kelly wrote: "Recently I was in the studio pre-Grammys with Pharrell Williams working on something... ;) he was wearing the infamous hat!
"If you know anything about my fashion sense you know that I am a huge fan of Vivienne Westwood!!!!! So naturally one of the first things out of my mouth was oh my god you are wearing my favorite Westwood hat. (sic)"
Kelly previously made a special appearance in Pharrell's Happy video.
