Earlier, a 23-year-old student, Ms R claimed that she had dated Aaron for three months.
She also claimed that after finding out that Aaron was also chasing after her good friend, M actress, she broke up with him.
Hong Kong tabloids reported that M actress is suspected to be Michelle Wai, who bears slight resemblance to Aaron's ex-girlfriend Lynn Hung.</p>
According to report, Aaron took on the filming of Philip Yung's new film "Port of Call" and recommended to the director for Michelle to take on a role.
Aaron was said to have even suggested to add in a bed scene with Michelle in the film, reported Asianpopnews.
Michelle has since dismissed the report and said: "I am not the rumoured M actress and I do not know Ms R."
However, Michelle admitted that she was offered a role in "Port of Call".
Asked if she had declined the role because of the bed scene, Michelle said: "There was a sex scene. I do not wish to film such scenes and I was feeling down at that time, so I declined the role."
