Jenna Fischer teamed up with her trainer in LA yesterday to fit in some exercise and showed off her growing baby bump in a form-fitting top. The Office actress is expecting her first child with her husband Lee Kirk, and flashed a wide smile during her afternoon workout. Jenna, who is originally from Missouri, has been focusing on some philanthropy as she enjoys a break from the set of her hit series. She teamed up on a fundraising auction for victims in her home state who were affected by the Joplin tornado, and one lucky bidder will win a set visit to The Office courtesy of her efforts. She and the rest of the comedy's cast and crew are coming up on their first full season without Steve Carell at the Dunder Mifflin helm, but rumors that James Spader might be the new boss and take on a role even bigger than Michael Scott's have started to gain traction.
