Frail Burt Reynolds is locked in a battle for his life as he struggles to recover from open-heart surgery — but friends fear he’s lost his will to live and is facing his final days.

"I think his son Quinton is terrified he’s going to lose his dad," a close source told The ENQUIRER.

The 74-year-old star underwent quintuple bypass surgery Feb. 22 and as this exclusive ENQUIRER photo shows, the screen legend appeared fragile and dejected as he left JFK Medical Center in Atlantis, Fla., on March 2.
