Sylvester Stallone reacts to Piers Morgan's birthday tribute

British journalist Piers Morgan was among thousands of people to share birthday tribute to Hollywood superstar Sylvester Stallone, who turned 80 on Friday.

“Happy 80th birthday to one of my all-time favourite film stars Stallone - the man who gave the world Rocky Balboa, and the most inspiring ever movie speech. Just don’t ever arm-wrestle him,” wrote Morgan while sharing multiple throwback photos with the Hollywood veteran.

The journalist on Saturday took to his Instagram stories to draw fans' attention to the response he got from Stallone on his post.

The actor wrote, “Thank you, my friend. We’ve had so many good moments together and I’m proud to say I’m friends with one of the very very best of all time. Keep punching my friend. Hope to see you soon.”
