Another child is on the way for "30 Rock" star and creator Tina Fey. The actress best known for her portrayal of Liz Lemon on the NBC comedy series has announced that she is expecting during a taping of "The Oprah Winfrey Show" on Wednesday, April 6.

Tina's representative has confirmed the happy news to People magazine, adding that she is already five months into her pregnancy. The baby will be her second child with composer husband Jeff Richmond. The seven-time Emmy Awards winner already has a daughter named Alice Zenobia Richmond, who was born in September 2005.

40-year-old Tina stopped by the "Oprah" show to promote her new memoir, "Bossypants", and an upcoming "Saturday Night Live" reunion. The episode itself is scheduled to air next Tuesday, April 12.

The "Date Night" actress has shared her consideration on having another child in "Bossypants". "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. Most kids have at least two," she wrote. "Who will be my daughter's family when my husband and I are dead from stress-induced cankers? She must have a sibling."
