Wait, what? Beyonce changed her Met Gala dress because of RiRi?

This is such a silly report but interesting. At the Met gala last week, Beyonce showed up an hour late. Now they are saying she was late because she saw Rihanna's dress & went back home to change

Sources tell Us Magazine,

"While looking on Instagram on her way to the swanky NYC event, Beyonce saw what everyone was wearing and made her driver turn around and go home so she could change into another dress she had on hand, an insider tells Us. She wanted something racier and sexier for the carpet."

Rihanna was the last person to walk the red carpet and Beyonce showed up an hour later
