Leave it to dad to post embarrassing baby photos on the internet. 

Like every other tech savvy celebrity, Pretty Little Liars — and Once Upon a Time — star Julian Morris posted a photo of his dear old dad on Father's Day. The message was short and sweet: "Love you dad," he wrote, accompanied with a throwback photo of his shirtless father on the beach. So how did papa Morris return the favor? By posting a photo of pint-sized Julian and his little sister Amy rocking all-denim ensembles from the '80s. 

"Happiest dad on Father's Day @julianmorris @amy_morris1 thank you for the love," he wrote. Aw! Okay, so maybe that was an adorable way to thank his children for being the best — and could toddler Julian be any cuter? Sure, he may have grown several feet and some facial hair, but Julian's signature smirk is still the same. Paging Dr. Wren. We need you in Rosewood ASAP. 

How adorable was Julian as a kid? Check out a recent photo of Julian and Amy below. Did you know it was him? Sound off in the comments!
