Pharrell Williams has dropped by the set of the Entourage movie to film a cameo appearance.

Entourage star Adrian Grenier shared a picture on his Instagram account of Pharrell, alongside other stars guesting on the show including an all-grown-up Haley Joel Osment and Russell Wilson.

Grenier captioned the photo, "Might have been the back to back cameos that got us through but after a long 14 hour shoot, wrapping at 2am, we are one more week closer to the #EntourageMovie thanks to @Pharrell @mcuban @dangerusswilson @hjosment @jerrycferrara @mrdougellin"

The Entourage - The Movie Facebook page posted a picture of Pharrell posing with Jeremy Piven's character Ari Gold.
