It's reportedly a girl for Serena Williams and her fiancé, Reddit cofounder Alexis Ohanian.

According to multiple reports, the 35-year-old tennis pro delivered her first child on Friday at St. Mary's Medical Center in West Palm Beach, Florida. The baby, whose name is still unknown, reportedly weighs 6 pounds, 13 ounces.

Williams revealed her pregnancy in April. Once she went public with the news, it became clear that she not only competed at the Australian Open in January when she was about seven to eight weeks pregnant at the time, but that she won the tournament without losing a single set.

In an interview published by Vogue in August, Williams said that she suffers from a medical condition that made her pregnancy potentially life-threatening. In 2011, she was hospitalized with bilateral pulmonary embolisms following foot surgery. That makes her prone to blood clots during pregnancy. She took medication to avoid the clots while carrying her first child.

Williams and Ohanian, 34, were engaged in December 2016. The couple haven't announced a wedding date.

A representative for Williams didn't immediately respond to INSIDER's request for comment.
