Especially when real‑life K‑pop idols step into the role of fictional K‑pop stars on screen, it is like getting the best of both worlds.

Below are standout roles from K-dramas where our favorite idols donned a stage persona within a story, giving fans a double dose of entertainment.
4. IU In The Producers
IU is already established as one of the best singers in the K-pop industry. Back in 2015, she took on the role of Cindy, a fictional superstar in The Producers.

With this role, IU not only established her stronghold as an actor but also brought an authenticity to her character, showing the harsh realities of fame.

The drama presents an incredible mix of idol life, backed by a medical condition. With real-life idols playing their fictional self, the drama certainly adds an extra element of excitement for the audience.
