Jenna Fischer: It's A Boy!

Pregnant Jenna Fischer is appearing on The Tonight Show on Tuesday and was asked by host Jay Leno if her parents were thrilled over the upcoming birth of their first grandchild. "This is the second grandchild," Jenna corrected, "but first grandson."

Jay pointed out that The Office star had used the word 'grandson,' and that's when Jenna confirmed that she and husband Lee Kirk are expecting a boy.

"This is the exclusive, Jay," the mom-to-be said. "When I went to my movie premiere the other day a reporter asked me if I knew what I was having, and I said I do, but I’m not sharing that yet because I’m [going to] have Jay be the first to know.”

And Jenna must have been feeling generous because she gave Jay yet another scoop: the baby is due in the fall.
