Arnold Schwarzenegger is putting his considerable weight behind a bodybuilding book written by hunky Magic Mike star Joe Manganiello. The former Mr. Universe, 65, has been forming a bromance with the beefcake True Blood actor since they filmed together for the action movie Sabotage. The friendship has progressed so mightily that the Nanny-impregnating former Governator has even penned the foreword for the workout manual. "Arnold and I got on really well during the film and have become friends," said the What To Expect When Youre Expecting star, 36. "It is a really great honour that he is writing the foreword for me." The book, titled Joe Manganiellos Evolution: The Cutting-Edge Guide to Breaking Down Mental Walls and Building the Body Youve Always Wanted is set to be released in January 2014. Here are some images of the two muscle-bound celebrities.. .Pictured: 14 Jan 2013, Los Angeles, California, USA --- Actor Joe Manganiello arrives at the premiere of The Last Stand held at Graumans Chinese Theater in Hollywood..
