The news comes less than two months after Mara, 34, and Phoenix, 44, sparked speculation that they were taking the next step in their relationship after the Social Network actress was spotted wearing a large diamond ring on her left hand. Rooney Mara and Joaquin Phoenix are ready for their next big role - as spouses! The Girl With the Dragon Tattoo actress and the Joker star are engaged, Us Weekly can confirm. Super-conventional! That’s why I’m not sure I really believe it. So it makes sense that after more than two years together, they would talk about getting married. Joaquin has seemed especially happy and especially domesticated with Rooney. They’re a really cute, offbeat couple and I enjoy the thought of them cooking vegan food together and composting together and going to karate together. She dumped her boyfriend at the time, and then she started living with Joaquin. They worked together that year, then suddenly they got together and went all-in rather quickly. Rooney Mara and Joaquin Phoenix have been together since late 2016.
