"I'm having another boy!" she told the mag. "We're very excited to give our son a brother."
Garcia, 45, and her husband, businessman David Conrod are already parents to 3-year-old son Lucas.
Lucas is very excited for the arrival of his little bro, Garcia said. "We told him and he's very happy to be a big brother. He's waiting for the baby to come more than we are."
With the baby due this December, the now six-months pregnant Garcia said that her craving of choice is watermelon.
"Lots of fruit and vegetables but mainly watermelon. It tastes better than ever, so I've been indulging in that," she said.
