The actors met in 2011 while on the set of the crime film The Place Beyond the Pines, which was released in 2012, in which they starred as couple Romina and Luke, alongside Bradley Cooper and late GoodFellas actor Ray Liotta.
Though neither have ever confirmed that they have married – Eva will however occasionally call Ryan her husband – the two have been together since 2011, and share two daughters: Esmeralda Amada, 8, and Amada Lee, 6.
Eva took to Instagram Tuesday to pay tribute to their anniversary, sharing a slew of photos from their time on set together, the first and only time they have been co-stars.
The first couple of photos see the two fully in character, with Ryan sporting bleached blonde hair and his arms decked out in tattoos, while they're both holding and playing with a baby.
Other snapshots seem to prove it was really love at first sight, as they posed looking at each other with glistening eyes, embracing each other, and riding on the back of a motorcycle.
"Luke & Romina," Eva wrote in her caption in between two black heart emojis, noting that a friend of hers sent her the photos, and told her it had officially been ten years since the film was released.
"Feels like lifetimes ago," she also noted, which was followed with droves of fans gushing over the adorable throwback photos of the two.
"Eva sees her man all over social media & she's like, 'Let me remind everyone he's mine,'" one fan cheekily said, noting how a brand new trailer for Greta Gerwig's Barbie was released earlier in the day, in which Ryan stars as Ken alongside Margot Robbie as Barbie.
Others also wrote: "Aww cuties," and: "Real life Barbie and Ken," as well as: "Come back on screen together please we miss you!" plus another fan added: "One of my favorite movies ever. You were both incredible in it."
