Meryl Steep's gang is all here!

The three-time Oscar winner stepped out Sunday evening with her family by her side for the 3rd Annual Academy Museum Gala at the Academy Museum of Motion Pictures in Los Angeles.

Accompanying Streep, 74, were her four children with ex Don Gummer: son Henry Wolfe Gummer, 44, plus daughters Mamie Gummer, 40, Grace Gummer, 37, and Louisa Jacobson, 32. Also along for the glam evening out were Henry's wife Tamryn Gummer, as well as Grace's husband Mark Ronson.

To celebrate their mother as she was given the Icon Award, her children were dressed in glamorous black-tie attire. Her daughters, all actresses, wore black like their mother; from left, Grace wore a long-sleeve black gown, Mamie wore a Bevza number with slashes at the bodice, and Louisa wore a silver-embroidered A-line gown with an Edie Parker clutch.

The outing comes six weeks after PEOPLE confirmed that Streep and the father of her children had quietly ended the romantic nature of their relationship six years ago.

“Don Gummer and Meryl Streep have been separated for more than 6 years, and while they will always care for each other, they have chosen lives apart,” a representative for Streep said in a statement to PEOPLE.

Streep and Gummer met through the actress's brother in 1978, when she was mourning the death of her boyfriend of two years, fellow actor John Cazale. Six months later, in September 1978, she and Gummer were married in the garden of her parents' home. They went on to welcome Henry, Mamie, Grace and Louisa.

Although the pair has not been seen publicly together since the 2018 Oscars, the Sophie's Choice actress was seen wearing her wedding band as recently as Oct. 20 at the 2023 Princesa de Asturias Awards in Spain.

In addition to being a mother of four, Streep is a grandmother of five. Son Henry shares two children with wife Tamryn, while daughter Mamie is mom to two kids with husband Mehar Sethi and Grace has one child with husband Ronson, 48.

Streep recently opened up about a fun tradition she and her daughters have — namely, two specific movies that they watch over and over again.

"Mean Girls and Romy and Michele’s High School Reunion are pretty much religious texts in my house," Streep told Vogue in a conversation published in September, amid the Mamma Mia! 15th anniversary.

"Those are the movies that I rewatch with my girls the most to this day," the actress added.
