Jane Krakowski isn't the only "30 Rock" star with a baby on board.

Tina Fey, 40, is pregnant with her second child, her rep confirms to UsMagazine.com. Fey announced the news herself during a taping of "The Oprah Winfrey Show" on Wednesday. (The episode is scheduled to air April 12.)

The Saturday Night Live alum is five months along. She and her husband, composer Jeff Richmond, also have a 5-year-old daughter, Alice.

In her new memoir "Bossypants" (out now), Fey wrestled with the idea of having another child.

"I thought that raising an only child would be the norm in Manhattan, but my daughter is the only child in her class without a sibling," Fey wrote. "Most kids have at least two."

"Who will be my daughter's family when my husband and I are dead from stress-induced cankers?" she cracked. "She must have a sibling."
