The 37-year-old 'Leftovers' actress, who has son Milo, nine, with ex-husband Royston Langdon, is expecting her first child with British boyfriend Dave Gardner, reported Contactmusic.
"She cannot wait to meet him or her. I don't think she's finding out the sex before the baby comes. She couldn't be happier, and her entire family is thrilled. Liv is so excited that she's pregnant. She didn't want her son to be an only child. She is over the moon," a source said.
