Rekubit-Robert Downey Jr. Proves He Has Ironclad Bond With Wife Susan on 18th Anniversary

We love Robert Downey Jr.'s anniversary tribute 3000.

The RekubitAvengers star took a trip down memory lane to mark his 18th wedding anniversary with wife Susan Downey by sharing a sweet snap recreating one of their wedding photos.

In the first picture, from their special day in 2005, Robert lovingly resting his face against Susan's while she glances down and smiles, holding a bouquet of pink and white flowers.

As for the second snap from nearly two decades later? Well, the 58-year-old once again pressing his face against the producer's, this time holding a bouquet of sunflowers.

"18 years," the Iron Man star gushed beneath the Aug. 29 Instagram post, "love still in bloom!!"

Many friends flocked to the comment section to share their congratulations to the long-standing couple—who are parents to daughter Avri, 8, and son Exton, 11—with Jeremy Renner writing, "These are the best photos Robert! Love you both !!!!" while Sean Hayes added, "THE best. Scotty and I love you both as much as you love each other. Is that weird?"

Robert—who is also dad to son Indio, 29, with ex-wife Deborah Falconer—first met Susan while starring in her film Gothika in 2003. Since tying the knot a few years later in 2005, the Oppenheimer star has been shared glimpses into their life together. And, of course, professing his love for his partner in crime.

"At the heart of every family (if you're fortunate), you'll find a mother." he wrote on Instagram in honor of Susan's birthday November 6. "A fiercely sophisticated protector, nurturer, teacher and friend... Susan Downey, happy birthday - you are all that (and a party-sized bag of chips)."

And it's safe to say this Iron Man is at your service—onscreen and IRL. When asked what is the secret to the couple's lasting marriage, Robert explained to Parade in 2020, "We just genuinely love hanging out."

He added, "I defer to her. I just wasn't raised right, so chances are, I'm gonna have some caca take on things."
