The first Monday of May of every year is the annual Met Gala where anyone that's anyone is invited in pop culture!
Though once the celebs enter the museum everything is secretive, but what everyone watched for is the outfits on the red carpet.
One of this years co-chair is Serena Williams. And not only did she show up in a gorgeous neon yellow gown, but also showed up in matching neon Nikes! That has to be a Met Gala first!
