Last month, Michael Douglas revealed to Jimmy Kimmel that his father wanted just a small birthday celebration as opposed to the extravagant affair the family usually presented year after year.

"So, he was 100, big birthday, big birthday. The trouble is, when you're 100, you don't really want a big birthday," Michael explained. "I threw a big party for him, it was great."

"101. You know, 'OK, let's have a nice party.' 'Again? I don't...' 'Dad, it's 101 years old. You have to have a birthday.' 102..." he continued. "He's begging me, he's got tears down his eyes. 'Let's just have dinner, the family together. Bring the kids.'"

Monday also spelled congratulations for the Douglas family as Michael also received a Golden Globe nomination for Best Performance by an Actor in a TV series – Musical or Comedy, for "The Kominsky Method." He'd won the award at the last Golden Globes back in January.
