MONSTA X’s promotion schedule might be jam-packed these days, but the boys have proven that they still know how to have fun!

While appearing as special guests on the March 29 broadcast of KBS CoolFM’s “Lee Hong Ki’s Kiss The Radio,” MONSTA X members Shownu, I.M, and Jooheon performed a lively cover of BIGBANG’s hit single “FXXK IT.”

In the clip, which was shared via KBS KONG’s official YouTube channel, vocalist Shownu struggles to keep up with the English part of the first verse and tries passing the part to I.M. However, the rapper is only able to keep up for a few more lines before playfully admitting defeat by saying, “Oh my God.”

The slip-up sets a fun mood for the rest of the cover and the boys can be seen cheering each other on and helping one another with their parts.

During the same radio broadcast, MONSTA X’s Jooheon reveals why he struggles with contact lenses. Plus, fans will have the chance to see even more of MONSTA X’s playful antics on next week’s episode of “Weekly Idol.”
