This seems fishy. What if she performs on both? I mean of all stars to choose why did they choose her to begin with

I mean - she's Rihanna and that's enough. But in Grammys case it is never easy to get a performance if you're not a nominated artist- you need a lot of starpower to do that. But at the same time, Bruno is a equally appealing artist, who is also nominated this year and supposedly slated to perform/appear at the Superbowl and the Grammys. Why not him then?
What I want to say is: She for sure is performing at the Grammys, but I wouldn't discount a Super Bowl appearance too.
