Mr Hero Zhang did not know it until Nov 7 - his birthday - when he woke up in his Toa Payoh home and was shocked by several messages on his mobile phone.
His friends were eager to tell him about the "juicy headlines" on entertainment news websites in China and Hong Kong. One headline screamed "Cecilia's new Singaporean toy boy".

The pictures had been taken from Mr Zhang's blog, which he had uploaded earlier this month. In two of the photos, he and Cheung, 33, appeared close as they posed for his selfies.
