In "The Break-Up", Carlton Lassiter is seen talking to Lily over the phone at the police station. Lily is not seen.
While the baby's gender was not announced, Carlton did refer to the baby as "little buddy" and was later found writing a letter to the unborn child, addressed as "Dear son", as he assumed the child was male. In "Shawn and Gus Truck Things Up", Lily was born, and all previous assumptions went out the window.
Lily Nora Lassiter is named after Timothy Omundson's two daughters, Lily and Nora.
