Sylvester Stallone is sure his Expendables buddy Arnold Schwarzenegger will recover from open-heart surgery and be “big and better than ever.”

But Stallone says he doubts that Schwarzenegger, 70, will give up the cigars both stars enjoy.

“Some things you just can’t give up, stogies and breathing,” Stallone told photographers Friday about quitting cigars, according to a video posted on TMZ.

Stallone, 71, said, “doubt it,” when asked about the prospects of Schwarzenegger dropping the cigar habit once he recovers.

“He’s doing great. He’s a brave man,” said Stallone.

Schwarzenegger is in stable condition after undergoing emergency open-heart surgery, his spokesman Daniel Ketchell confirmed via Twitter Friday afternoon. Ketchell noted that the actor and former California governor was awake. “His first words were actually, ‘I’m back,’ so he’s in good spirits.”

Schwarzenegger was at Los Angeles’ Cedars-Sinai Medical Center Thursday for a catheter valve replacement. When the experimental procedure resulted in complications, doctors decided to open him up. This was Schwarzenegger’s fourth cardiac surgery.

But the star has continued to enjoy cigars despite the risk of heart health dangers.
