HONG KONG superstar Andy Lau and his wife Carol Chu were spotted arriving at the KL International Airport (KLIA) on the special day of Sept 9 (09-09-09), reported China Press.

A passenger on the same 8.50am CX723 flight with Lau and Chu was quoted as saying that Chu and two of her female relatives were spotted checking in at the express lane counter at Hong Kong International Airport.

"They were checking in for business class seats with many pieces of luggage.

"Chu did not wear make-up and was wearing a grey T-shirt, jeans and flat shoes," the daily quoted the passenger as saying.

Lau was wearing a white T-shirt, blue shirt and white sports shoes.

Upon arrival at the KLIA, the duo were spotted wearing face masks, with Lau nodding his head at some passengers and staff who recognised him.

The couple was later escorted out by airport security personnel through the VIP lane.

According to the daily, the couple is believed to be planning a marriage ceremony within 100 days of Chu's father's death in Malaysia.
