Williams does not want to know sex of baby till it’s born.

And on the red carpet of the Met Ball last night, Serena Williams flaunted her baby bump in a emerald green gown.

While most expectant women opt to find out the gender of their child before the birth, Serena has revealed that she won’t be doing the same and is planning to have a surprise.

The athlete said, “We’re waiting. [It’s] a surprise. We call it ‘baby’.”

Williams is expecting her first child with her fiancé, Reddit co-founder Alexis Ohanian.

Making her first red carpet appearance since announcing her pregnancy, Williams was glowing as she cradled her growing bump at the annual bash, in New York.
