In celebration of the Caitlin McHugh's 31st birthday over the weekend, boyfriend John Stamos and McHugh spent the day at Disneyland in Anaheim, California, and brought along Stamos' Fuller House co-stars, Bob Saget and Dave Coulier, as well as his former Grandfathered co-star, Josh Peck. Gushing over his girlfriend, the 53-year-old actor posted a photo of himself dressed as Tigger while kissing McHugh, who was wearing a Winnie the Pooh costume.
