Sylvester Stallone trades silver screen for small screen with new mobster series

Actor Sylvester Stallone joins ‘Fox & Friends’ to discuss his new TV series ‘Tusla King’ and reflects on his career with top box office hits across several decades.

Max Casella is opening up about his prepubescent years. 

The now 55-year-old actor shockingly revealed he didn’t hit puberty until the age of 27.

During an interview with Page Six, he explained he had pituitary dwarfism – a growth hormone deficiency characterized by unusually short height – according to the media outlet.

"I was given testosterone," he said. "I was on growth hormones; I’m still on those things. My body didn’t go through the change by itself."

"I have a malfunctioning pituitary gland from birth and basically had to jumpstart my puberty by pumping me full of testosterone and growth hormones to get me to grow because it wasn’t happening. I was 25, and I hadn’t even shaved."

Despite Casella’s delayed puberty allowing him to play certain roles much younger than his actual age, he noted that it was a terrible experience. 

"It was a horror show," he remarked. "I couldn’t talk about it. No one understood it. It’s like the trans community today talks about body dysmorphia and feeling like, ‘I’m in the wrong body,’ absolutely my experience. Absolutely. I was a man trapped in a little boy’s body throughout most of my 20s until they finally pumped me full of testosterone."

Meanwhile, the "Doogie Howser, M.D." alum added that after meeting Stallone he had an "almost sh—in your pants moment."

"I had his poster on my wall when I was 10 years old, and now I’m acting with him? It’s surreal," "The Sopranos" star confessed, according to the media outlet.

"I’ve acted with a lot of big stars: Leonardo DiCaprio, Brad Pitt, Johnny Depp. Sometimes it’s up or down, your experience with them, but nobody like Sly, who was such a superhero to my 10-year-old self. This was like my boyhood dream."
