Edward Norton has reportedly become a dad for the first time.
The Moonrise Kingdom actor and Canadian film producer Shauna Robertson welcomed a son last month but the news has only just emerged, reported Us Weekly.
An insider said the couple are "thrilled and excited for parenthood".
It has also been reported that Edward, 43, and Shauna, 37, quietly tied the knot last year.
Us reported that the pair, who had been dating for several years, got engaged in 2011 and exchanged vows in 2012.
Fight Club star Edward has never publicly commented on his engagement or Shauna's pregnancy.
Shauna has worked as a producer on films such as Superbad and Pineapple Express.
