Joaquin Phoenix and Rooney Mara welcome first child together, reportedly named River

"A beautiful son."

Joaquin Phoenix and Rooney Mara have reportedly welcomed their first child together, a baby boy named River. The couple, who have been together since 2016, reportedly welcomed their first child recently, following a pregnancy that had not been confirmed by the pair. According to Buzzfeed, the news was revealed by director Victor Kossakovsky, whose film Gunda is executively produced by Phoenix. Kossakovsky revealed the news to press during a screening of his film at the 2020 Zurich Film Festival. 

According to the director, Joaquin could not attend the premier because he "just got a baby," a "beautiful son."

Kossakovsky also said that the couple named their son River, after Phoenix's late brother who died in 1993.  Phoenix and Mara began a relationship back in 2016 after meeting on the set of 2013 film, Her. They later starred together in He Won't Get Far on Foot and Mary Magdalene, both from 2018. In July 2019, it was reported that the couple were engaged and in May of this year that they were expecting their first together. Neither the pregnancy nor the birth has been commented on by either Phoenix or Mara. Phoenix, who recently starred in Todd Philips' Joker, paid tribute to his late brother early this year while accepting the Oscar for Best Actor for his role in the movie. "I have been a scoundrel in my life. I've been selfish," he said. "I've been cruel at times, hard to work with, and I'm grateful that so many of you in this room have given me a second chance. "I think that's when we're at our best, when we support each other, not when we cancel each other out for past mistakes, but when we help each other to grow, when we educate each other, when we guide each other toward redemption. That is the best of humanity. "When he was 17, my brother wrote this lyric. He said, 'Run to the rescue with love, and peace will follow.'"
