Any Ideas?

My little sisters has started to like Michael a couple months پہلے and she now knows every song that he wrote. She knows the lyrics سے طرف کی دل and whenever im watching my MJ ویڈیوز she always asks if she can watch too. This is great because she is only 6 years old and she's always telling her دوستوں that Michael is the best and he will always be the king. So the problem is that she told me that she wanted to go to an MJ concert.....she doesn't know that he passed away. My mom told me that I have to tell her that he's gone...but I dont know how, she's been crying because she wants to go. Any ideas on how I can tell her?
