UPDATE: After his initial post, Sylvester Stallone shared another picture with the message, "Sorry, didn't mean for this picture to go up before saying that I'm very happy and please understand my brother is so em motional because he is just very protective and only wants the best for me. Life is good!"
You can't keep Sly on the ropes.
After losing an Oscar in an upset on Sunday, Sylvester Stallone posted an inspiring message to his fans on Monday, writing, "To all the 'real Rocky's' of the world, Please hang on to your dreams, NEVER GIVE IN , NEVER GIVE OUT , NEVER GIVE UP! thanks for the support."

The 69-year-old actor was expected to win Best Supporting Actor for his performance in the Rocky rebirth film, Creed, but was surprisingly defeated by Mark Rylance, who won for Bridge of Spies. It was the Rocky star's first nomination in nearly 40 years, after he was nominated for Best Actor for the original movie in 1977.
Frank Stallone came to his brother’s defense after the loss with an angry tweet. “The Academy should be ashamed of themselves,” he wrote. “It's as clear as the nose on your face that Sly won. Mark who? It's total Hollywood bulls**t."

Creed's leading man, Michael B. Jordan, notably didn't receive a nomination, one of the many snubs that fueled the #OscarsSoWhite movement. In fact, at one point during the show, Oscars host Chris Rock even remarked that the actor should have received a nod for his performance.
After learning he was the only person nominated from Creed, Stallone revealed he considered boycotting the ceremony, but the film's director, Ryan Coogler, talked him out of it.
