Jenna Fischer is expecting a boy, she revealed Monday on "The Tonight Show with Jay Leno."

"The Office" actress told Leno she'd been asked very recently on the red carpet whether the baby was a boy or a girl, but refused to answer at the time, allegedly because she wanted to tell Leno first.

So, the host observed, "Like a lot of girls, you were saving yourself for Jay!"

Oh my. So, yeah, um, the baby is due in late September. What were we just talking about?

Fischer, whose movie, "A Little Help," opens Friday, took the opportunity to address "the nation" on a few issues important to pregnant women, including cleaning up around the sink in the public restroom, agreeing to take a seat rather than doing the "hover and tinkle," and the nature of true hunger.

If a pregnant woman says she's hungry, Fischer said, don't ask her what she'd like to eat: "You should just throw food at her."

"Don't offer me a salad with vinaigrette dressing," she explained. "I want spaghetti bolognese. I want it immediately. Or I'm going to eat your foot.

"That's kind of how it goes."
