The star of Showtime's The United States of Tara and her husband David Galafassi's son was born on Friday in Australia, her rep tells PEOPLE exclusively.
"Toni Collette, her husband David Galafassi and their daughter Sage Galafassi are excited and proud to announce the arrival of their baby boy, Arlo Robert Galafassi," the rep says.
"He was born on Good Friday making it the greatest Friday, indeed!" the couple said in a statement.
Collette was understandably absent from Saturday's premiere of her new movie Jesus Henry Christ at the Tribeca Film Festival in New York City on Saturday.
"She is doing well," the film's director Dennis Lee told PEOPLE on the red carpet.
Julia Roberts is the executive producer of Jesus Henry Christ, which tells the story of a child genius who was conceived in a petri-dish and is determined to find his biological father.
Collette married musician Galafassi in 2003. Their daughter Sage is 3.
