Jenna Fischer Welcomes Baby Boy!

Dundler Mifflin fans have something to celebrate! The Office star Jenna Fischer has mirrored her role of Pam on the sitcom since she's officially a mom. Jenna and her husban Lee Kirk are proud parents of their son, Weston Lee. Weston was born on September 24.

A rep told Access Hollywood, "Mom and baby are doing great." Jenna announced her pregnancy in May and two months later she told Jay Leno on The Tonight Show that she was expecting a boy.

Life apparently imitates art since her role on the hit show apparently sparked an interest of motherhood for Jenna who loves working working with twin babies on The Office.

Last fall she told The Los Angeles Times, “They got the cutest babies in town to play our baby. Pretty much any time we get to see baby Cece is great.”

Congrats, Jenna and Lee!
