"My Pop!" he tweeted. "Successful proactive quadruple bypass surgery this week! A great Blessing indeed!"

The same photo was shared to the official Facebook page of The Way, a film which stars both Martin and Emilio, with a slightly longer message that read, "Martin extends a big thumbs up and a BIGGER heart felt 'THANK YOU' for all your well wishes and prayers. He wants to wish you a very Merry Christmas and sends you all a mighty blessing!"

Emilio, 53, shared a lengthy post to the Facebook page one day earlier, informing fans and friends of the family of Martin's procedure.

"The decision to operate on his heart was a proactive one, not an emergency situation," Emilio explained. "With my mother Janet and our family by his side and under the coordination of his extraordinary team of cardiologists, doctors and nurses, my father displayed great courage, strength and humility as he took on this challenge."

"Not surprisingly, he is recovering beautifully, out of the ICU and is expected to not only be home for Christmas, but be 100% by the time he returns to work on season three of the Netflix series Grace and Frankie early next year," he added.

Martin's other son, Charlie Sheen, is dealing with some health issues of his own, as just last month, he appeared on the Today show and confirmed reports that he was HIV positive. Hours after the 50-year-old Two and a Half Men star made the public announcement, Martin spoke at CME Group's Global Financial Leadership Conference in Naples, Florida, where he revealed he had been encouraging Charlie to reveal the diagnosis "for several months," along with the rest of the Sheen family.

"This morning, as I watched him alone, reveal his deepest, darkest secret, I couldn't believe the level of courage I was witnessing, and that it was my son," Martin said. "I left him a message, and I said that if I had that much courage, I would change the world."
