Actor Edward Norton has welcomed his first son with fiancée Shauna Robertson. US Weekly reported that the baby was actually born in March. USA Today reported that the couple got engaged in 2011 after being together for six years. Robertson is a Canadian film producer.

Norton has not publicly addressed his engagement to Robertson or the pregnancy. The Huffington Post reported that an insider said that they parents were "thrilled and excited for parenthood.

A source said according to US Weekly, "Ed is really excited for fatherhood. He helped pick out a stroller for the baby."

The Daily Mail reported that Robertson has worked with Judd Apatow on movies like The 40-Year-Old Virgin as well as Knocked up. Norton and Robertson have started a fundraising website, CrowdRise together which raises money for various charitable causes.

Norton has starred in movies such as "Moonrise Kingdom," "American History X,"
 "Primal Fear" and "Fight Club" amongst others. He also recently began production of the movie "Birdman" which will co-star Emma Stone, Zach Galifianakis, Michael Keaton and Naomi Watts.

The Belfast Telegraph reported that the movie is about "a desperate washed up film star who battles his own ego to reclaim his career by joining an off-the-wall Broadway play." reported that "In an amusing bit of casting, former Batman Michael Keaton will play the role of the former superhero actor. Emma Stone will play his daughter and assistant, newly released from rehab. Naomi Watts will play a lead actress in the play. Zack Galifiankis will play a "conniving" producer. That's a murderer's row of talented folks, particularly for a comedy."

The movie is directed by Alejandro Gonzales Inarritu who has directed intense films such as "Amorres Perros," "21 Grams" and "Babel."

It is set to open in 2014. In the past Norton has been romantically linked to Salma Hayek and Courtney Love.
