Beyonce showed up a whole hour late for this year's Met Gala [click here if you missed that].
Was Rihanna to blame..?
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.
