Henry Winkler Has Proud Grandpa Moment with His Daughter and Three Adorable Red-Headed Grandsons

The family stepped out for This Is About Humanity's 6th Anniversary Soirée at Winkler's home in Los Angeles on Aug. 24

This Is About Humanity's latest event this weekend was a family affair for Henry Winkler and his daughter Zoe!

On Saturday, Aug. 24, the Happy Days alum, 78, and his only daughter Zoe Winkler Reinis were joined by her sons at This Is About Humanity's 6th Anniversary Soirée — an annual event highlighting the organization co-founded by Reinis.

This Is About Humanity, which focuses on separated families in border cities, holds its yearly soirée in Los Angeles. And this year, Reinis' three young boys posed for snaps with their mom as they came by to support the family!

Held at Henry and Stacey Winkler's home, the event benefitted the TIAH collective food-relief kitchen, the Immigrant Defenders Law Center and the This is About Humanity Binational Fund for ICF. It featured bites from Michelin-Star chefs and also recognized Florence Azria for her contributions to the org's food relief efforts, according to a press release.

Wearing polos and button ups in shades of blue, the kids, who are named Ace, Jules, and Gus, according to a profile on their mom on The Worker's Circle website, smiled for a camera alongside Reinis, who wore a lace and floral dress. The mom of three also spoke at the event with fellow This Is About Humanity co-founders Elsa Collins and Yolanda Selene Walther-Meade.

Winkler himself wore a plaid-and-tan blazer, pink button-up, blue jeans and white sneakers for the event as he posed for snaps with his daughter.

Other famous faces including Eva Longoria, Lauren Sánchez and Julianne Hough were in attendance.

Winkler is the father of three adult children: Zoe, Max Winkler, and Jed Weitzman, from his wife Stacey's previous marriage to Howard Weitzman. He's also a proud grandfather of "six and three-quarters grandchildren," as he told PEOPLE in August: Ace, Jules and Gus, as well as India, Lulu, Francis Joan and one on the way.

"It is different, completely different than being a parent, " he said at the time, "but it is filled with the same emotion... Every one of them is different. You have to approach each one completely differently."

As Winkler revealed to PEOPLE this month, while they may be "different," all of his grandkids have to follow the same rules when they spend time with him.

"Now the rules in the house, and there are a few, only a few, are the same," he said. "When the youngest granddaughter is sleeping, there is no fighting, there is no yelling. They are in charge of their friends to keep it down. "

"No matter what age they are, from 14 to 7, they have to clear their dish," he added.
