People reports that during a press conference last week, Nastase was overheard commenting on Serena's unborn child to a reporter, saying, "Let's see what color it has. Chocolate with milk?"
Williams wasn't too happy with Nastase's comments and responded via an Instagram post yesterday.
"It disappoints me to know we live in a society where people like Ilie Nastase can make such racist comments towards myself and unborn child, and sexist comments against my peers," Williams wrote.
"I have said it once and I'll say it again, this world has come so far but yet we have so much further to go. Yes, we have broken down so many barriers — however there are a plethora more to go," Williams continued. "This or anything else will not stop me from pouring love, light and positivity into everything that I do. I will continue to take a lead and stand up for what's right."
