Historically a girl wins Lil champs and that too from the Bengal Kolkatta region.that may change this time round; just like the senior rounds.They will also bring the past champions n top 5 singers to sing wtih them.
You may be right. We still have some girls from that region like Antara Nandy and a boy Abhigyan Das. I think there are at least one more.
Are you sure that last years top 5 will sing with the new lil champs? Then I might heard Aamir too. I check with him whether he is invited. So far not otherwise he would mentioned it.
