The actor was 81 years old when he died, but he had been full of life until his last breath.
"Larry was the happiest person I have ever met," said the President of White Bridle Society Sheree Wilson, a longtime friend of Larry who co-starred on the original Dallas. "His bathroom mirror had the statement 'Don't Worry, Be Happy, Feel Good.' And that is how he lived his life."
His Dallas co-stars Linda Gray (who played his wife Sue Ellen) and Patrick Duffy (who played his brother Bobby) were reportedly at his bedside when he died, according to The Sun.
Hagman is survived by his wife Maj Axelsson, their daughter Heidi Kristina, their son Preston and five granddaughters.
