The actor, 78, who is buying a $25 million dollar home for his three daughters in tony East Hampton, New York, spontaneously busted a move during a clothes fitting on Friday.
The Tulsa King star was barefoot and trying on a muscle hugging navy blue sweater and jeans when classic Motown tune, More Love, by Smokey Robinson and the Miracles played.
The Rocky star couldn’t help but let the the music do the talking and started moving lithely around the space in time with the beat.
Luckily, someone was on hand to capture the moment.
‘I was caught off guard while going through a clothes fitting for an upcoming project— great song though!’ the action hero explained.
This dance will go viral!!’ one fan boldly predicted. ‘ Sly showing off his skills I was amazed by this video!!’
‘Boss man got the moves… KP sly,’ wrote an admirer.
‘You got the moves! Are you doing a fitting for a sequel to Magic Mike?’ joked a fan.
Stallone has never studied dance, but he may have gotten some of his moves when he was growing up and his late mother, Jacqueline, was managing a group of lady wrestlers.
‘They weren’t really wrestlers, they were kind of unemployed pole dancers,’ the Creed actor told Jonathan Ross in January 2016.
‘And I just frolicked around and did the best I could,’ he said.
The Judge Dredd star also surprised former frenemy Arnold Schwarzenegger with an impromptu waltz at the Cannes Film Festival once.
‘We danced the waltz,’ the Terminator star, 77, told Women’s Wear Daily in May 2017.
‘It was 1991, I believe. Sylvester was here for a film, and I was promoting Terminator 2: Judgment Day, and up until that point we didn’t really hit it off well,’ he said.
‘We were very competitive and trying to derail each other at every angle and every possibility. And then, somehow, because we were working for the same company, we hugged at a party right about here,’ he explained.
‘The Gipsy Kings were playing and we were holding onto each other and they said, “Do you want to dance?” and he says, “Yeah.” And so we were dancing, we were waltzing, around and around and around,’ Schwarzenegger explained.
‘Then we all of a sudden stopped and he said, “God damn it, you’re leading, I hate that,”‘ Sly’s future The Expendables co-star revealed.
In the 1997 Stallone went full disco on Saturday Night Live in a skit featuring with Will Ferrell and Chris Kattan as the Roxbury Guys.
The audience was astounded at his nimble moves as he stole the dance floor from the cast members and was joined by a group of kids and young adults dressed in T-shirts and suits.
The actor has also appeared on social media yukking it up with his daughters. With experience with the waltz and disco, could an apperance on Dancing with the Stars be next?
