Recently on Weibo, a netizen in Mainland China claimed that Cecilia Cheung brought a man back to her house in Hong Kong.
According to Asian E-News Portal, the duo could be heard shouting on the roof top in the middle of the night.
Six days ago during the promotion campaign, Cecilia responded and denied the incident.
She said: "The incident reported on Weibo is false and it is considered slander without any solid evidence. To the culprit, please delete it on Weibo."
The netizen then deleted the post quickly.
Just two weeks ago, Cecilia Cheung was spotted lunching with a Singaporean man.
