At the Met Gala on Monday night, Serena Williams took a moment to speak with Vogue's André Leon Talley. The 35-year-old attended the famous New York City event with her fiancé Alexis Ohanian.

Talley asked the question on everyone's mind: What is the gender of her baby?

But the mom-to-be said, "We are waiting." The couple is referring to their first child together as "baby" until the due date in the fall.

While the biggest question was the baby, this one was just as loaded: Where will Williams and Ohanian live? Ohanian, the co-founder of Reddit, resides in San Francisco, but Williams didn't give a very clear answer.

"That's the question of the hour, right?" Williams said. "I couldn't be stuck in a more beautiful place."

The world No. 1 currently resides in Palm Beach Gardens, Fla.
