Pregnant Tina Fey's Baby Bump Pictures

Tina Fey stopped trying to hide her baby bump last night when she stepped out for an interview on the Late Show With David Letterman with her stomach on display in a tight black dress! She stopped by to chat with host David Letterman about her new book Bossypants, though her interview doesn't air until this Friday. Tina was more covered up over the weekend when she chatted up the best-selling book at a Manhattan Barnes & Noble and went for a walk with her husband and 5-year-old daughter Alice. She wrote about motherhood, her career, and her childhood in the memoir, and her shout-outs to her home state of Pennsylvania just earned her a sweet writeup in the Philadelphia Inquirer.
