Sylvester Stallone Shows Off Full Head Of Grey Hair

The legendary action hero shared a clip of himself in the back of a car, looking drastically different from how he usually does - his jet-black locks were noticeably absent.

In the clip the 73-year-old actor strikes his fist towards the camera and says: "Keep punching, my friend. Keep punching."

Underneath the clip he wrote: "Sometimes I wake up, I feel like doing nothing. Just relaxing. Just very true. If anyone says different, they're lying - it's human nature.

"Then you roll over, get a little mad at yourself and realise to get anywhere you've got to make a deposit in the GOAL BANK, so I'll go back to my favourite phrase and do it!"

Fans seemed pleased to see Sly with his silver do, with one person commenting to say: "You should keep the grey hair!" and another writing: "Wow, you look great."

According to the news outlet, Sly is also in negotiations to pen the script and to reprise his role as the boxer.

Having recently starred as Rocky in the Creed movies, Sly went on to say that he has a deep attachment to the character after playing him for four decades.

"It's like my brother," he said. "It's the only voice that I can say what I want without being ridiculed, or being silly, or being precious or sentimental, because he is that way.

"Rocky can't keep quiet. He just talks and talks and spills his guts. And as a writer, if you do that quite often, it looks as though you're just lost in the world of exposition.

"But he's actually saying something, and because of the way he speaks and his naivety and gentle quality, you listen. Rocky can say things that my other characters can never say."
