Aug. 22, 2013— -- Jennifer Love Hewitt is going to get more than just Christmas gifts this holiday season.

"The Client List" actress, 34, told ABC News last night at a Pampers event in New York City that she is due in December.

If that wasn't a big enough gift, the birth of Hewitt's baby will come with another big surprise – the gender of the child. "I don't know," she said of whether it's a boy or a girl. "It's one of life's greatest surprises and we wanted to keep it that way."

The biggest transition for Hewitt, who announced her pregnancy and engagement to "Client List" co-star Brian Hallisay in June, is that she's amazed by the changes to her body.

"You wake up in the morning and you go, "Wow, this is no longer my body," she said. "What's going to happen today? It teaches you to not be in control and I've been a control freak for a long time."

She's also suddenly a sweets person.

"I like cake all of the sudden," the "I Know What You Did Last Summer" star said. "I never was a cake person."
