Joaquin Phoenix is a dad.
The "Joker" star and his fiancé, actress Rooney Mara recently welcomed a baby boy.
Phoenix's good friend director Victor Kossakovsky revealed the happy news during the Zurich Film Festival.
This is the first child for the 45-year-old Oscar winner and his 35-year-old fiancé.
Although the ultimate private couple never confirmed Mara's pregnancy, media outlets reported the news back in May.
While no details have emerged about Phoenix and Mara's new bundle of joy, Kossakovsky did share one piece of information.
The baby's name.
