As Us Weekly reports, several of Serena's famous friends turned out for the party, including Eva Longoria, Kelly Rowland, La La Anthony, and Ciara—and yes, they 'grammed.

Everyone dressed in costumes, wearing everything from poodle skirts to pearls.

The party was, appropriately, held at Nick's '50s Diner in West Palm Beach, Florida.

This just set a new bar for baby showers.
