Tennis champion Serena Williams came clean about how she accidentally went public with the news of her pregnancy, which she intended to keep private a bit longer.

Williams “says she was taking a personal photo of her progressing pregnancy on Snapchat when she accidentally pressed the wrong button and made the post public,” the AP reports. “The photo of the tennis superstar in a one piece bathing suit was captioned ’20 weeks.’ Despite the lack of information, it immediately made headlines around the world last week. Her publicist later confirmed the pregnancy to The Associated Press.”

Williams talked about the incident during an interview this week with Gayle King at the TED2017 Conference in Vancouver. The AP notes that Williams said her Snapchat gaffe wasn’t a big problem, because she was planning to put the word out soon anyway.

The AP report adds: “Williams says she plans to return to the court after becoming a mom, adding, ‘My baby is going to be in the stands, hopefully cheering for me and not crying too much.'”
