Rumors that Hong Kong film star Andy Lau's wife Carol Chu is pregnant are once again swirling. "Evidence" of the pregnancy is shots of Chu at the airport in Kuala Lumpur recently, protecting her stomach and wearing a facemask.

Lau, 49, and Chu, 44, married in 2009, but reportedly had trouble conceiving, according to MSN.com, until celebrity Kelly Chen recommended a Hong Kong fertility expert.

It has also been reported that Lau has bought a $3.8 million house in Malaysia, for his wife to get away from Hong Kong and bring the child to term in peace.
