Rihana cancelled her performance because of Beyonce?

Beyonce wore this white sheer dress to 2016 Grammy Award. She was there to present the Record of the year which went to "Uptown Funk" by Mark Ronson featuring Bruno Mars.
Some say this may be why Rihanna cancelled her performance last minute, because she knows it will be all about Beyonce. But the reason Rihana gave was due to bronchitis problem.




But why is that celebrities don't like mixing with those they think are higher than them?

Beyonce is indeed a goddess no wonder Jay Z.......

Some are meant to be bigger than you as you are meant to be bigger than others, so no one scares me.
