Chinese actress Zhang Ziyi is angry at the recent sex tape rumor involving her husband Wang Feng, who denied the allegation on Tuesday.

A video clip and several images allegedly linked to veteran rocker Wang Feng and singer Xu Geyang, the girl that Wang is going to mentor in the reality singing contest show "Sing! China." In the clip, a woman who looks very much like Xu was having sex with a man who didn't show his face but the caption said it was Wang.

Wang Feng's studio swiftly issued a statement to denounce the rumor widely circulated on the internet.

"Someone maliciously spread erotic images and a video on Weibo and WeChat, which extremely harmed Mr. Wang Feng's reputation, we have to make it clear that Mr. Wang Feng has nothing to do with the images and the video," the statement reads, adding that the studio has handed this issue over to the lawyers and will find anyone responsible for making up this rumor.

Zhang Ziyi, who gave birth to a baby girl Xing Xing with Wang, responded to the rumor on her Weibo account this morning, "The evil perpetrator's bottom line now is so low, it is beyond our imagination. To Xing's daddy, let me know who smears us when you find out; Xing's mum will personally take care of him or her."

The TV show "Sing! China" also issued an official statement denying the woman in the video is Xu Geyang by comparing the places of tattoos on the two's bodies. They said they had already called the police, and will sue those involved, including some media outlets, for slander and spreading the vicious rumor.
