Inside Serena Williams' '#ShakeRattleandRoll' baby shower

Eva Longoria, Kelly Rowland and La La Anthony were among the guests.

The tennis star's baby shower was held Saturday at Nick's 50's Diner in West Palm Beach, Florida, and had a 1950s theme, with the mother-to-be sporting a pompadour, poodle skirt and black-and-white saddle shoes.

Williams and Ohanian, 34, announced they were expecting back in April, which was approximately four months after the two revealed on Williams' verified Reddit account that she and Ohanian were engaged.
