Jenna Fischer will welcome a baby boy in the fall. The actress famous for her portrayal of Pam Halpert on NBC's "The Office" shared details of her first pregnancy while promoting new movie "A Little Help" on "The Tonight Show with Jay Leno" last Tuesday, July 19.

"This is the next grandchild," the "Hall Pass" actress corrected hostJay Leno when he asked her if her parents were ecstatic to have their first grandchild during the TV meeting. She went on to reveal that her baby would be her parents' first grandson.

"This is the exclusive, Jay," the 37-year-old sustained on. "When I went to my movie opening 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 since I'm [leaving to] have Jay be the first to know."

Jenna also spilled, during the chat, when she is likely to give birth to her first child with screenwriter husband Lee Kirk, whom she married in July 2010. "September we're in what they call the home widen," so she shared.

The "Solitary Man" actress announced she is pregnant with her first child through her representative back in May. Just days prior to the statement, she was spotted presentation off her baby bump while going out to Red O eatery in Los Angeles.
