Serena Williams made a statement about her baby's gender after her sister Venus referred to her future niece or nephew as "she."

"I think the surprise of knowing what you are going to have on that very special day you give birth is prob the best surprise you can ever have!" Serena Williams wrote.

Serena also explained that the use of pronouns and baby names are a joke—or technically a bribe.

"I am always joking with my sisters to see what favors I can get them [to] do for me next..." she added. "I did not grow up with any brothers, only sisters and we all say "she" more than "he."

The 35-year-old has said previously that she's waiting to find out the gender. She's approximately six months pregnant and due in the fall.

In Paris, her coach Patrick Mourataglou said Serena could be back as soon as the Australian Open.


“For anyone, it sounds impossible, because it’s too short a time after you give birth,” Mouratoglou said. “But Serena is Serena. There is no rule that you can apply to Serena. She has a body that is not anybody’s body. She has a will that is also completely unusual. She is one of a kind.

"I never see any limits for her and put any limits to her, because that would be wrong. So if she says Australian Open, it’s going to be the Australian Open."
