Socialite Theresa Po Wing-kam is suing TVB for defamation over comments by a prime-time comedy show character she claims is based on her.
Ms Po, 48, whose high-profile relationship with ex-disc jockey Hung Chiu-fung has made headlines since 1999, claims her reputation suffered after remarks by a character on Screen Play on the Chinese Jade channel.
One of the show's recurring characters, a 'Miss Po', was also referred to by the nickname 'Po Po', according to the writ launching the suit in the High Court on Wednesday.
Ms Po, who is suing Television Broadcasts Ltd for unspecified damages, says her surname is not common in Hong Kong and she is known in the media as 'Po Po'.
She took offence at remarks in episodes broadcast on January 25 and 26 this year and since made available on video, concerning 'Miss Po's' relationship with an ex-disc jockey known as 'Fung Fung', which is also Hung Chiu-fung's media nickname.
'The plaintiff was widely known to have a romance with a disc jockey, Hung Chiu-fung,' the writ says.
