MORE than 20 nude photos of late Taiwanese singer Teresa Teng and retired actress Lin Ching Hsia are missing.

This was confirmed on Thursday by Teng's older brother, Mr Teng Changfu, reported Apple Daily Taiwan.

Mr Teng was speaking to reporters in the lead-up to his sister's 15th death anniversary yesterday.

Teng died at 42, after an asthma attack in Thailand.

Photos showing the two bikini-clad Taiwanese entertainers on a beach off the Mediterranean Sea have been circulating on the Internet.

And rumours abound that both women even took nude photos of themselves.

It seems that while Teng was warm and elegant onstage, there was also a passionate and bold side to her, as the photos show.
