Channing Tatum and wife Jenna Dewan were locked at the hip and laughing over dinner at Asia de Cuba inside L.A.’s Mondrian Hotel. Dewan was co-hosting the private dinner with her The Playboy Club costar Laura Benanti in honor of the NBC show and Benanti’s birthday. Guests, including Taye Diggs, dined al fresco and enjoyed sparkling wine with the meal. But when it was time to pay, Tatum and Diggs (nicely) dueled over who would pick up the check. In the end, Tatum won out – and he triple tipped the server.
