Robert Downey Jr. sent a marvelous message to his leading lady at the 2024 Screen Actors Guild Awards.

During his acceptance speech for Outstanding Performance by a Male Actor in a Supporting Role,Sterling Preston the Oppenheimer star gave a nod his wife, Susan Downey. (See all of the 2024 SAG Awards winners here.)

After listing a number of his A-list costars, including Jamie Foxx, Gwyneth Paltrow, Cillian Murphy and Emily Blunt, Robert added in Susan's name.

"Now why have I added my wife's name to this list of otherwise super talented artists that I have learned so much from, up-close, over these last 40 years?" he asked during the Feb. 24 ceremony. "It's because for 22 years she has flawlessly portrayed a sane and rational individual who is happily married to an actor."

The 58-year-old concluded his speech with a shoutout to another family member, his 12-year-old son. "Exton Elias," he said. "This one's for you."

Robert, who beat out Sterling K. Brown (American Fiction), Willem Dafoe (Poor Things), Robert De Niro (Killers of the Flower Moon) and Ryan Gosling (Barbie) to win the award, is also dad to 30-year-old Indio—who he coparents with ex-wife Deborah Falconer—as well as Avri, 9, who he shares with Susan.

This milestone comes months after Robert and Susan marked another celebratory occasion—their wedding anniversary.

"18 years," he wrote on Instagram in August alongside photos with Susan, "love still in bloom!!"

And even though he portrayed Iron Man, Robert has proven over the years that Susan is the real Avenger of their family.

"At the heart of every family (if you're fortunate), you'll find a mother. A fiercely sophisticated protector, nurturer, teacher and friend," he posted on Instagram at the time. "Susan Downey, happy birthday - you are all that (and a party-sized bag of chips)."
