She may be one of the greatest tennis players of all time, but her Snapchat game could use a little work.

Serena Williams said Tuesday that the Snapchat post from last week that revealed her pregnancy was an accident.

"You know how social media is -- you press the wrong button and..." she told "CBS This Morning" co-host Gayle King during an interview at the TED2017 conference in Vancouver. Williams said she was simply trying to save the photo to her phone.

The post, a selfie that showed a swimsuit-clad Williams sporting a baby bump above a caption reading "20 weeks," appeared briefly last Wednesday before being deleted. A spokeswoman for Williams later confirmed that the athlete was expecting.

The news made it clear Williams was pregnant in January when she beat sister Venus to win the Australian Open. That win -- Williams' 23rd Grand Slam singles title -- put her past Steffi Graf for most Grand Slam singles titles in the Open era. She still trails Margaret Court, who won 24 majors but bagged 13 of those before the Open era started, in 1968.

As for her tech chops, perhaps Williams can get a little training from her fiance. In December, she announced that she'd become engaged to Reddit co-founder Alexis Ohanian.

At the TED2017 confab, interviewer King joked that she wouldn't have expected Williams to play matrimonial doubles with "a nerdy geek," according to Business Insider.

"I wouldn't either," Williams replied, but "he's very loving and he's very kind. He's very considerate."
