In Touch Weekly quotes a friend as saying: "This wasn't planned, but Naomi and Liev are thrilled," a friend told the magazine, predicting "They'll probably be married before the baby is born."

The couple have been together for almost two years. Watts is said to be just entering her second trimester and is barely showing. However, a pal has revealed that Naomi has planned not to take any roles until after the baby is born. "She'll be such a great mom," the friend says.
