The Romania captain, who was suspended from the Fed Cup for abusing the British team and the referee in a playoff, was heard speculating whether Williams’ child would be “chocolate with milk?” per the BBC. 

Williams has weighed in on Instagram and said, “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.”

“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,” she continued. “Yes, we have broken down so many barriers - however there are a plethora more to go. 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.”

Williams, who is pregnant with her first child, thanked the International Tennis Federation for launching an investigation into the comments.
