Actor Jung Woo Sung is facing criticism after private messages between him and a netizen were leaked online, coinciding with the scandal involving model Moon Gabi, who recently gave birth to their son.

The messages that were released on social media depict Jung calling the unnamed netizen and complimenting her work.

He allegedly said he hadn't wanted to message her in the first place but contacted her anyway after seeing her appear on his feed.

"What a cool career," he wrote, and when a confused netizen wondered if his account had been hacked, Jung responded by telling her he knew her and admired how much she enjoyed her work.

During their chat, Jung talked about his recent trips for filming and posted a sky view from inside his car.

He reflected on the long hours of filming and the difficulties that brings, adding: "Moving around is hard. You must have lots of late nights too.

Near the end of their conversation, Jung asked if he could leave his mobile phone number. "Can I give you my number?" he inquired.

The netizen then replied, "Do what suits you," and Jung soon gave her his number and told her to call.

These messages came to light, and since then, social media has erupted, with people in shock and others speculating about the actor's personal life and behavior as the scandal continues.
