Rock singer Ella has lodged a police report to put an end to escalating rumours that she and her sister, Jojie, had been involved in a sex video.

The 36-second video clip, allegedly featuring Ella, whose real name is Nur Zila Aminuddin, and her sister, Jojie, engaging in sexual activities on board a cruise ship, was making its rounds on the Internet and had been given extensive coverage in the newspapers.

In the clip, a woman, supposedly resembling Ella, was seen clad in a blue towel while another couple in another corner of the room were engaged in a sexual act.

Ella ( right ), when contacted by the Star, said: "We were shocked when we found about it.

"I don't know what people's intentions were when they claimed that we were the persons in the clip. We hope to find the real culprit behind this," she said.

Malay Mail quoted Ella as saying: "Trust me. If it was really me, I would have gone into hiding."

"I don't know what were the intentions of these people who posted these clips and claiming that it was me. It's just amazing the things that people are willing to say and do."

The daily also reported that Ella has dismissed possibilities that her fans and the public will believe that she is the person featured in the sex video.

Faces in video not clear

Meanwhile, Jojie said that she and Ella wanted to ignore the rumours but we decided to lodge the report after getting numerous phone calls from friends and fans of Ella.

"We have watched the clip but the (faces were) not clear. Our family members were also upset, so we decided to lodge the report. If it was really us, of course we would not dare to make any report," said Jojie.

She said that the video could affect their reputation and did not deny the possibility that the culprit intended to deny Ella's career as a singer.

"Fortunately, Ella is strong enough to handle the matter. Though she was initially mad and frustrated, she still managed to handle it. Our family has also been very supportive as they know us better.

"Maybe we will hold a press conference later for further clarification on the case," she said, adding that this was the worst rumour spread about her sister so far.
