We can only imagine that his new girlfriend, model and actress Caitlin McHugh, is loving this mishap, too. ET caught up with Stamos' Fuller House co-star Jodie Sweetin backstage at Dancing With the Stars in March, where she couldn't stop gushing over Stamos' brunette beauty.

"I actually met her a couple days ago. She is delightful," Sweetin revealed. "She's really sweet and we are welcoming her into the family. They're adorable, and we really like her."
