Alyson Hannigan: The ‘How I Met Your Mother’ star was pregnant through much of the long-running sitcom’s fourth season, though her character, Lily Aldrin was far from expecting a baby. The show filmed mostly in the winter, allowing for her to wear some looser clothing and large jackets, though she was able to famously show her bump in one episode, where her character had eaten too many hot dogs. She gave birth to she and husband Alexis Denisof’s first daughter, Satyana Marie on March 24, 2009. When she became pregnant with her second, child, Keeva Jane (who was born May 23, 2010), her pregnancy was written into the show’s storyline, and Lily gave birth to a son, Marvin.
