He may be back at work promoting his latest film, but Channing Tatum is still basking in the glow of his fairy-tale wedding. The brooding star said “I do” to his girlfriend of over three years, actress Jenna Dewan, on July 11 in Malibu. “Just being able to say ‘my wife.’ It’s great to be able to say it,” Channing told In Touch about his favorite part of marriage at the G.I. Joe: The Rise of Cobra premiere at Andrews Air Force Base in Camp Springs, Md., on July 31. The actor’s G.I. Joe co-star Marlon Wayans was one of 220 guests at the nuptials. “Oh man, it was so fun!” Marlon gushed to In Touch at the screening. Channing and Jenna met on the set of their 2006 dance hit Step Up.
