After f(x) leader Victoria showed up for the premiere of former EXO member Luhan's new flick "The Witness", there is a buzz that the two are in a secret relationship.

As a Kpop star and an artist of South Korean record label SM Entertainment, the presence of Victoria at the event captured the attention of many movie goers mainly because of Luhan's legal dispute with the firm.

The main dancer of the girl group looked gorgeous in her black outfit while she attended the press conference along with Chinese entertainers Deng Chao, Liu Yifei and others in Beijing on 28 October.

Although many of her fans were looking forward to her romance with Luhan, the Kpop star revealed that she attended the event after receiving an invitation from the female lead of the movie Yang Mi, according to Koreaboo.

"The Witness" is a Chinese remake of the popular Korean movie, "The Blind", and it revolves around the investigation of a mysterious murder case and two of its eyewitnesses. While Luhan plays the role of a delivery boy who claims to be a witness, Yang Mi portrays a blind girl who was apparently travelling with the killer at the time of the incident. Other cast members includes Zhu Yawen, Wang Jingchun, Liu Ruilin and Lai Yi.

The movie, directed by Ahn Sang-hoon, hits the big screens of China on Friday, 30 October.
