Vanity Fair's December art issue has Hollywood hunk Brad Pitt up in arms. Brad Pitt appears on the steamy cover in a pair of white, wet boxers.

Vanity Fair is also showing a video of Pitt, wearing white socks and boxers, standing silently as he gets soaked by water. At the end of the clip, he raises a water pistol and fires towards the camera reports Canada.com.

"We are very disappointed that Vanity Fair has chosen to put an unauthorized cover on their magazine,� the 42-year-old star’s representative said in a statement issued Tuesday. “It seriously makes me question their integrity and motives."

Reps for Vanity Fair tell TMZ, "In a letter dated October 5, 2006, and sent to Pitt care of Brillstein-Grey [Pitt's managers], Wilson informed Pitt that a still image from his portrait was going to be featured in the December art issue of Vanity Fair." A source says that Pitt never saw the letter.

"Brad Pitt posed for a Robert Wilson video portrait, and in the photo release (signed by Pitt), agreed to allow Wilson to use the portrait or any images from that sitting in connection with any publicity on Wilson's video project. Vanity Fair decided to do a story on Wilson's video portraits and obtained rights to the entire collection of photographs from those sittings, which included Pitt's.

The video art installation will be exhibited in New York early next year.
