We all know and love her as Pam Beesly, receptionist for Dunder Mifflin Paper Company and wife to Jim, played by John Krasinski, on the ever hilarious hit comedy/mockumentary, ‘The Office.’

Fischer appeared on Jay Leno’s ‘The Tonight Show’ on Tuesday night, saving a special piece of news for her host. She slyly revealed the sex of her little bun in the oven!

When Leno asked whether this was the first grandchild for her parents, Fischer responded, “This is the second grandchild, but the first grandson,” to a rapturous applause from the audience.

This was the first time the sex of the baby was revealed to the public and boy was the host delighted!

Along with her husband Lee Kirk, Fischer will be anxiously awaiting the arrival of their new baby boy with a late September due date.

As for her character Pam, the pregnancy will be written into the script! Are the lovebirds Jim and Pam expecting again? We’ll have to wait and see.
