BbaekGa shocked the nation with his comments about his celebrity ex-girlfriend during a recent airing of SBS PowerFM's Cultwo Show.

The singer didn't sugarcoat when he addressed how different she is in person vs in public.

As reported by Koreaboo, BbaekGa labeled his ex-girlfriend as "fake" in her portrayal on the program during a frank discussion with the hosts of the show.

He also called out her claim of being a vegetarian or vegan by stating, "I know how much meat she eats."

He went on to berate her habit of smoking saying, "She smokes a pack and a half per day."

She's so fake on TV. It's absurd. She claims to be a vegetarian or vegan, but I know how much meat she eats. And don't even get me started on how much she smokes. It's hard to keep my mouth shut. - Bbaekga as quoted by Koreaboo.

The revelations from BbaekGa did not end here. His ex-girlfriend started dating one of his friends while they were still together, he said.

"They claim it wasn't cheating, but I felt betrayed," he explained, expressing his feelings of betrayal after discovering their secret relationship.

I'm an avoidant type, so when I meet her during schedules, it's so awkward. The layers of her fake-ness are endless. [...] The funny part is, I used to hang out with that guy often, only to find out later they were secretly dating while I was with her. They claim it wasn't cheating, but I felt betrayed.

Even with fellow industry entertainer Hyoyeon of Girls' Generation advising him to be careful about oversharing, BbaekGa was sure no one would ever figure out who he referred to.

Those comments come off as some last vestige of bitterness from their past relationship.

This conversation has gained traction as fans and media outlets wonder how real a "celebrity" is in show business.
