Though the recent Allure cover girl strikes a typically sultry pose for the black-and-white cover, the accompanying "We're All Crazy for Eva" shoot with photographer Ellen von Unwerth takes a loopy turn.
The former Calvin Klein spokesmodel wears a red dress as she resists a nurse's attempts to restrain her in one photo, while another image sees her donning a blonde wig and a red suit as she calls for help.
Mendes -- rocking a long black wig, harem pants, and a semiconscious pose -- also bums a smoke from a nurse, tries to climb the hospital fence in a teased red do, and gets busted throwing her blonde wig in the pool.
All that's missing is the Lady Gaga-style straitjacket.
