It's not clear why the world is just finding out about this now, but 86-year-old Dick Van Dyke married his 40-year-old girlfriend Arlene Silver on February 29th.

He says, "It was on the spur of the moment, we just decided Leap Day would be the best time to do it."

Dick was married to Margie Willett, the mother of his four children, from 1948 to 1984. And he lived with a woman named Michelle Triola for more than 30 years...until her death in 2009. And, yes, that means he was living with Michelle for years before officially getting divorced from Margie.

Here's video of Dick and his new wife. Around the one-minute mark, they sing the theme from "All In the Family"...and it's awful.
