well with her reality show coming it will be soon, but i voted no, but knowing shania she wont use the show to see her personal life were gonna see shania at her best working to be the best she can be at singing, so it has to be this year!!
We don't know for sure if Shania IS definitely going to make another appearance, and I doubt she would sing a new song on Idol given the fact she probably hasn't recorded anything still.
