Japanese model Nana Komatsu, 20, appears to be cheating on Masaki Suda, a star of "Death Note: Light Up the New World" - with BIGBANG's leader G-Dragon.

On Sept. 18, Sunday, the official private Instagram account of the 28-year-old rapper was hacked, revealing pictures of him with his rumored girlfriend, Nana Komatsu. It was reported that G-Dragon's public Instagram account is "xxxibgdrgn," but the Kpop idol also has a private Instagram account under the name "peaceminusone."

One of the leaked photos showed G-Dragon and Nana Komatsu having dinner together, while the other one uncovered a woman, presumably the Japanese model, with her back to the camera - sitting on the BIGBANG leader's lap.

Not long after the news made clamor in the online world, G-Dragon immediately deleted his personal account. Further, he updated his public Instagram account with a photo of a man with his face wrapped, along with a caption that reads, "I can't handle people anymore."

Just a few days after the news of the leaked Instagram photo, various local newsstand in Japan, according to Soompi, claimed Nana Komatsu and Masaki Suda are a well-known couple, although the two are still unofficial. It is said that the two Japanese stars became close while working together for an upcoming movie titled "Drowning Love."

Considering the time that Nana Komatsu and G-Dragon's photographs were taken, local news outlet was keen to speculate that the former might be cheating on Masaki Suda.

Nonetheless, this is not the first time Komatsu and G-Dragon have been rumored to be dating. In early May, the two were spotted enjoying a dinner together at a steak restaurant in the Azabu region of Tokyo, Japan.

A video clip of Komatsu and G-Dragon's reported dinner date has also been posted on Instagram - showing the latter seating beside the former. However, many fans did not buy it, stressing that it is just a friendly dinner and nothing more.

It can be recalled that G-Dragon and Komatsu met last March to work on an intense photo shoot for Nylon Japan's May issue.

"I was very nervous about working with some who had me starstruck," Komatsu said in an accompanying interview, as quoted by All Kpop. "I told G-Dragon that it feels like a dream that I am working with him."

As of press time, neither G-Dragon nor Nana Komatsu has commented on the dating rumors.
