Madonna working with Pharrell?

Is Madonna hinting that Pharrell was in the recording studio with her? Not only this is the second time the Queen is posting on Istagram about him in a few days, but this second picture with Pharrell‘s hat was defenitely taken on the toilet of her recording studio in Los Angeles.

Pharrell forgot his hat! It’s mine now!
