The 29-year-old model recently revealed she and husband John Legend are expecting their first child and they haven't decided whether to find out the sex of their unborn baby yet.

But a source said: "Chrissy wants a baby girl so badly."

The couple announced the happy news just weeks after the Sports Illustrated beauty revealed they were "having trouble" conceiving and had sought IVF.

The insider added: "Chrissy and John are over the moon about the pregnancy. This is their dream come true.

"They did conceive via IVF. Chrissy is almost four months pregnant - they couldn't be more excited."

Although she found it tough revealing her heartache to the world, the blonde beauty later admitted she's wanted to speak out about her private struggle for some time.

She said: "I just wanted to talk about it for so long ... It didn't feel right to tweet, 'Ugh, doing my IVF shots again.' "

The duo are planning to raise their child in California, as they want to be close to Chrissy's sister Tina, who lives in Las Vegas with her toddler.

The source told Life & Style magazine: "They recently moved back to LA after selling their cramped one-bedroom condo in New York City."
