Meanwhile, Serena - who defeated her sister Venus to be crowned victor of the Australian Open in January - recently revealed her pregnancy announcement was an accident.
The tennis champion attended the star-studded ceremony with her fiancé, Reddit co-founder, Alexis Ohanian.
Serena Williams has always been handsome.
"I never felt pressure to get married, and I can't say I'm the marrying type", she told Gayle King.
Williams confirmed her pregnancy after speculation emerged when she accidentally posted a Snapchat of herself with a caption that said she was 20 weeks pregnant. Williams posted a message to her future child, via Instagram, that read "I can't wait to meet you".
Some of those that tennis followers must be itching to find answers to include how the absence of the world's number one will affect the Women's Tennis Association (WTA), and which players will most likely benefit if they grab the opportunity. "I couldn't be stuck in a more handsome place". That killer smile, soulful eyes and ideal skin have long turned heads, but never has she looked as lovely as she does right now. I can't wait for you to join the player's box next year.
Williams' baby is not even born yet, but they are already a target of a racial joke.
"Winning for me is super addictive", she said last week.
Clearly, Williams and Ohanian are a happy couple, and will soon be incredible parents.
