Malaysian model Lisa Ch'ng & TVB actor Mat Yeung reveal how their surprise marriage proposal got foiled

Malaysian model Lisa Ch'ng and Hong Kong actor Mat Yeung have revealed how their marriage proposal didn't quite go according to plan.

In a recent YouTube show, the couple – who married in Kuala Lumpur on Aug 2 – shared how Yeung, 45, had hoped to surprise Ch'ng, 39, with a proposal after a decade of dating.

However, his plan was quickly foiled when he tried to find out her ring size through mutual friends, inadvertently raising suspicions.

Things became even harder to keep secret when their friends and relatives began dropping hints, eventually leaving Ch'ng – who's based in Hong Kong – with little doubt that a proposal was coming.

"Our friends and relatives were simply too excited after hearing about the proposal and accidentally let the secret slip," she said, laughing.
