This hottie actor visited Good Morning America to promote his new movie, he but ended up trying on some fancy headgear, too!
Apparently, some pageant girls were also guests that morning, and he jokingly wore one of their crowns.
Or maybe he just wanted to feel like royalty for a day? After all, his famous wife is nicknamed the Dutchess.
Think you know who's playing dress-up? Find out after the jump...
It's Josh Duhamel, goofing around while promoting When in Rome on the morning show.
Josh is a busy boy...he's headed off to Sundance next to plug The Romantics, and we hear Fergie is joining him there.
Having a famous plus-one can't hurt. We all paid attention when a devoted Josh walked his wife (and Nine star) down the red carpet at the Golden Globes.
