Actress Laura Linney is a first-time mom at 49. The 'Big C' star and husband Marc Schauer quietly welcomed a baby boy, Bennett Armistead, on Wednesday, Jan. 8. We didn't even know she was pregnant!

Linney's rep confirmed the baby news to PEOPLE. Not much else is known at press time.

Bennett Armistead is the first child for Linney and Schauer, who wed in May 2009. Fellow actor Liam Neeson walked Linney down the aisle at the nuptials.

Congrats to the couple not only on their newborn son, who has a very big name, but on the fact that they were able to keep it hush hush. In Hollywood, concealing a pregnancy is nearly impossible to do.

We're looking forward to seeing pictures of Baby Bennett.
