This is what I found on entertainment weekly. Im going to see if Usher and Tiësto are performing at the half time show or if its a rumour.

I did a search on wikipedia on entertainment weekly to see if its a reliable source and found out that its an online magasine that’s based in New York City and its been running since 1990. So I know the is a reliable source.

Finally to double check I went on Snopes.com but it didn’t help with my research.
