On Tuesday's Tonight Show, while telling Jay Leno about her and hubby Ben Affleck's impending arrival, Garner revealed in a highly noticeable slip that the baby is a "she." "You can just start to feel really pregnant, like you are the hugest person on the face of the planet. ... I felt bigger and bigger like she ..." Garner then quickly (and conscientiously) covered her mouth with her hands, and the crowd cheered. She then paused, regained her composure, and took a sip of water. "Anyway ," she said. The actress and Leno then picked up their conversation.
