Childhood friends Paris Hilton and Kim Kardashian are working on a secret project. This is apparent from a Paris tweet, in which a video of the two can be seen.

“Secret project with Kim Kardashian”

“Secret project with Kim Kardashian. Can’t stop looking at my best friend’s ass”. Whether the latter is a hint to what the two are going to do is still a mystery. In the video, Kim asks viewers: “Guess what we’re going to do?”, To which Paris replies: “That’s another surprise.”

Fans guess that this is a musical project, because Hilton recently released a song entitled Best Friend’s Ass.
