Australian actress Nicole Kidman has sparked rumours she is pregnant after being photographed talking to her parents while new love Keith Urban pats and strokes her stomach.

The MOULIN ROUGE star, who has two adopted children with ex-husband Tom Cruise, reportedly accepted the country singer's marriage proposal just before America's Thanksgiving holiday (begs24NOV05), and sent a private jet to bring her parents from Australia to the US to meet Urban's family.

An onlooker says, "They certainly had something they were smiling about as they introduced their parents to each other.

"The whole time they were talking to her parents, Keith was rubbing her belly.

"They all had beaming smiles."
