Sacha Baron Cohen wears a bull costume during a photocall for his new film, 'Bruno,' at Las Ventas bullring. Madrid, Spain - 18.06.09

The outrageous Brit, who fell onto Eminem at the MTV Movie Awards dressed as a bare-bummed dove, posed as a gay Queen's guard for the London premiere of his new film on Wednesday (17Jun09), and was up to his tricks again outside Spain's bullfighting Mecca.

He appeared in character as outrageous Austrian fashion journalist Bruno - and donned a bull outfit for the film ceremony outside Las Ventas bullring.

He was joined by a troupe of hunky models, all dressed as matadors, who he invited to join him in his hotel room for a party.

Baron Cohen also bares all on the cover of July's GQ magazine.
