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.
