Just two weeks after announcing she was pregnant with her second child, the Oscar winner and her husband Adam Shulman showed up at the Hudson Theatre in New York City to check out Jake in "Sea Wall/A Life".
The couple worked together in the 2010 movie "Love and Other Drugs".
Hathaway announced her pregnancy news via Instagram on July 24, posting a black and white shot of herself sporting a baby belly, and captioning the shot: "It's not for a movie... #2."
The 36-year-old "Les Miserables" star added: "All kidding aside, for everyone going through infertility and conception hell, please know it was not a straight line to either of my pregnancies. Sending you extra love."
The actress first became a mum when her son, Jonathan, was born three years ago.
