Beijing - Chinese movie star Zhou Xun has announced her romance with Chinese-American television star Archie Kao of CSI: Crime Scene Investigation fame, after dating him for about a year, says NetEase website.

A black and white photo of the pair standing by a river was posted on her official Weibo page today, with a caption: "This is Archie, please look after us."

NetEase says the shot was taken in Paris on Sunday, before Zhou took a flight back to Beijing on Tuesday.

Kao, 44, was named one of the Hottest Bachelors by People magazine in 2006. Zhou, 39, met him in Hong Kong last year, around the time she was - mistakenly - rumoured to be romancing actor Nicholas Tse, 33.
