Arnold Schwarzenegger, Sylvester Stallone have hospital run-in

(CBS) Arnold Schwarzenegger and Sylvester Stallone have posed for photos together before, but probably not like this.

The aging action stars found themselves side-by-side in a hospital recently, where both were having shoulder surgery.

"After all the action, stunts & physical abuse shooting 'The Expendables 2' and 'The Last Stand,' it was time for a little tune up on my shoulder," Schwarzenegger wrote alongside the photo on his Whosay account Wednesday. "Look who was coincidentally waiting in line behind me for his shoulder surgery."

He added, "Now we're ready for another round of great times and action when we shoot 'The Tomb.'"

Schwarzenegger is 64, and Stallone is 65.
