Serena 'disappointed' by racist remark from Nastase about unborn child

Serena Williams won't stand for racist comments made toward her unborn child by retired tennis player Ilie Nastase.

"Let's see what color it has. Chocolate with milk?" Nastase said of the child between Williams and her fiance, Alex Ohanian, during a Fed Cup news conference, according to ESPN.

Williams responded to Nastase via Instagram on Monday:

Nastase also made unsubstantiated doping accusations based on Williams' physique earlier this month, in addition to making unwelcome advances on British captain Anne Keothavong as he repeatedly asked for her room number.

The 70-year-old former Grand Slam champion was ejected from a match Saturday for harassing a chair umpire.
