American actor, Joaquin Phoenix, and American actress Rooney Mara have become parents again. The celebrity couple is very secretive about their family life. The baby's gender is not yet known. For the first time, Mara’s pregnancy became known in February of this year. This is not the first child for Rooney Mara and Joaquin Phoenix. In August 2020, their first child, River, was born. His name is a tribute to Joaquin Phoenix's late brother, River Phoenix, who sadly passed away on October 31, 1993, at the age of 23. Joaquin Phoenix will star in the Joker sequel, Madness for two, later this year. The couple will soon appear in Lynne Ramsey's Polaris, which is currently in post-production.
