Look who's the big daddy now!
Throughout Dylan Sprouse's career, the actor has always been in shape, but he's never been mistaken for a gym rat. That's all changed.
On Instagram, Dylan, 29, posted a series of images and videos from the gym that show an enviable muscular body, which is something "The Suite Life of Zack & Cody" star has strived for.
"Used to wear a shirt in the pool as a kid so I decided in my late twenties I wanted to change my body and become a meat head," he wrote on Instagram. "This is my meat head post."
The images show Dylan with defined arms, a flat stomach and a chiseled chest.
"Been a long slog," he wrote of his fitness journey, "but I'm proud of the progress I've made and I ain't done yet."
Dylan's Instagram followers were stunned at his physique and commented with astonishment, as they lobbed words at him such as "beast," "incredible" and "hot."
Dylan got his start in acting as a 1-year-old while starting in "Grace Under Fire." He then got a big break while playing Adam Sandler's son is "Big Daddy" in 1999.
