Both IU and MBLAQ’s Thunder have proved to be close friends and it seems that the cover they did of Big Bang’s Lies has managed to surface on the Internet. There, we can see the adorable cover between the two!

IU is seen playing the guitar and the two seems to be pretty synchronized and harmonized at such a young age. Their cover definitely does give off a different feel and vibe from what we’ve seen from Big Bang.

Check out the cover below - would you want to see them make more covers or even have more duets?
