Today is the Lee Seung-gi episode of Hidden Singer.

I think this is seriously the first time I've seen someone imitate Lee Seung-gi's voice lol

I did guess that "Will You Marry Me?" in Round 2 was number 2, but

You can really tell that everyone practiced a lot.

It seems like they copy each phrase so perfectly that it's really hard to tell the difference.

I'm really surprised every time I watch Hidden Singer.
