John Stamos Hilariously Gets Mistaken for Rob Lowe While on Vacation -- See His Reaction!

By
John Stamos is quite the jokester.
The 52-year-old Fuller House actor took to Instagram on Thursday to share a hilarious video taken during a recent vacation getaway.
In the brief clip, which he captioned "#AwkwardVacationMoments" and tagged @robloweofficial, Stamos was hilariously mistaken for Rob Lowe by a not-so-up-to-date fan.
His reaction? Priceless!
"What, who did you think -- what's my name?" he asked. "Rob, what?"
Instead of correcting the confused woman, who was convinced he was "Rob Lowe," he let it slide, soaking in all the awkwardness.
"That's right, yeah, hi," he stated before flashing a cheesy smile for a selfie.

We have to give it to her, though. The two both have sexy smiles, similar hairstyles and bright-colored eyes. Oh, and did we mention they're the same age?
Looking so good must be such a hard feat for an "ex teen-idol," as Stamos so perfectly describes himself on Twitter.
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."
