Serena Williams turned back the clocks to 1950 for her baby shower over the weekend, just about one month before the baby is due.

Ciara, La La, Eva Longoria, Kelly Rowland and, of course, Serena's sister Venus were all in attendance for the 50s-themed baby shower which went down at a 1950s restaurant in Florida. 

Serena and here fiance, reddit co-founder Alexis Ohanian, still have not revealed the baby’s gender, instead referring to him or her as "Baby O."

Check out some of the photos below.
