Serena Williams has admitted that her pregnancy announcement was a complete accident.
The tennis star was using Snapchat to take pictures tracking the progress of her bump.
After captioning them with how far along she was in her pregnancy, she'd save them to look back on later.
But after she posed in a yellow swimsuit for her '20 week' picture, she accidentally sent it out to the world.
The 23-time Grand Slam champion had been taking a picture each week to see how much her bump had grown.
