Yet in an earlier Instagram post, Williams covered a happier topic.

The subject was her unborn baby, whom she wrote to while posting a picture of herself on holiday while cradling her baby bump.

My Dearest Baby, You gave me the strength I didn’t know I had. You taught me the true meaning of serenity and peace. I can't wait to meet you. I can't wait for you to join the players box next year. But most importantly, I am so happy to share being number one in the world with you…. once again today. On @alexisohanian bday. ???? from the world's oldest number one to the world's youngest number one. -Your Mommy
