Robin Williams' Son, Cody, Gets Married on Late Actor's Birthday

Robin Williams son celebrated him in the most special way -- by getting married on what would have been his 68th birthday.

His youngest son, Cody Williams, got hitched to longtime girlfriend Maria Flores on Sunday, July 21.

The wedding was held at the home of Robin's ex-wife and the mother of two of his children, Marsha Garces Williams.

The groom, who's 27 years old, looked sharp in his black suit and matching skinny tie.

His bride stunned in a puffy gown with sweetheart neckline and skinny straps. She paired the look with diamonds and her hair down and curled with a veil.

Cody's older sister, Zelda, captured the sweet moments during the celebration and posted them to Instagram on Tuesday.

The photos are no doubt adorable, but it's what Zelda wrote that really tugs on the heartstrings.

"The 21st of July has meant many things to me over the years. It’s the birthday of one of my favorite souls still on this earth, @junotemple. It’s the day Neil Armstrong stepped on the moon (as a space nerd, that’s pretty damn important)," she began.

"And it was the day my Dad was born, and the last day I got to see him. That last one had begun to usurp the joy of the first two in recent years... that is, until two days ago, when it became something new."

Continuing her moving message, Zelda turned the focus on her brother's day.

"On the 21st of July, 2019, it became the day I officially gained a new sister! To @mariaaafloresssswilliams and Cody, you are a light in all of our lives. I’m so grateful to have paid witness to your love over the years, to have watched you grow and care for each other in ways we should all be so lucky to experience," she wrote.

"You were already part of the family in my eyes, but now there’s an official slip of paper somewhere that agrees!" Zelda added.

Cody's blushing bride shared a few photos from their day of nuptials too, and guess who was in attendance? Susan Freaking Sarandon!!

The award winning actress, who stared alongside Robin in "Noel" and "The Big Wedding," took time out to come and support the couple on their special day.

Cody's wedding comes days after his older brother, Zak Williams, opened up to "Good Morning Britain" to remember their dad.

The 36-year-old, who's mom is Valerie Velardi, reflected on Robin's internal demons and the heartbreaking loss of losing him nearly 5 years ago.

Robin Williams died by suicide on August 11, 2014 at the age of 63.

The girls matched in black sleeved dresses with mesh tops and held a bouquet filled with white roses.

Maria showed off her perfect diamond which is one giant stone with several smaller sparklers surround it.

This appears to be before the ceremony because she doesn't have a wedding band on.

She also shared the moment they were introduced as Mr. and Mrs. Williams!

The duo look so happy underneath their multi-colored rose arch as they said "I do."

Congrats!
