The good news doesn't stop there. New mum and dad Jennifer and Brian Hallisay have also secretly tied the knot.
The couple's statement revealed that not only are the pair parents, but man and wife.
"Jennifer Love Hewitt and her husband Brian Hallisay are thrilled to announce the birth of their daughter," it said. "Autumn James Hallisay was born on November 26."
According to Us Weekly, a source added that the couple "got married recently in private."
Jennifer announced that she was pregnant with her first child back in June. Just one day later they confirmed that she and her Client List co-star boyfriend Brian were also engaged following a romantic trip to Italy in May.
"We're so thrilled and happy to start a family," they said at the time.
Jennifer, 34, and 35-year-old Brian have then been dating for around 20 months. The couple first worked together on NBC series Love Bites and reconnected on the set of Lifetime show The Client List.
The brunette star has made no secret of her desire to have children.
In a 2010 interview with Us Weekly, she admitted, "I would love to have babies — one day. I am obsessed with babies!"
