Everyone's favorite genius-billionaire-philanthropist just turned into a romantic.

In honor of the couple's 10th anniversary, "Iron Man" actor Robert Downey Jr. took to Instagram to remind his wife Susan just how special she is, posting a picture with the caption, "A perfect 10. Happy Anniversary, Mrs. Downey:"

A perfect 10. Happy Anniversary, Mrs. Downey.

Not stopping there, Downey also recently showed up on Instagram with his on-screen love Pepper Potts, aka Gwyneth Paltrow:

Now, everyone who counts on Downey's usual social stream of funny memes and videos doesn't need to worry. Iron Man still has plenty of those. But it's cool to see Tony Stark, who does have a tendency in the "Avengers" movies to be a little full of himself, taking a short respite from the comedy to spend time with the special ladies in his life instead.

Congrats to the happy couples on-screen and off. Anniversary gifts, assemble!
