Just because she’s engaged to a tech giant, that doesn’t mean Serena Williams has mastered technology. 
 
 The pregnant tennis champ opened up about her pregnancy to Gayle King at Tuesday’s 2017 Ted Talks conference held inside the Vancouver Convention Centre and revealed that her baby bump Snapchat was sent out to the world by accident. 
 
 “Well, actually it was an accident. I was on vacation just taking some time for myself and I have this thing where I’ve been checking my status and taking pictures every week to see how far along I’m going,” Williams, 35, said. “I didn’t tell a lot of people to be quite honest and I’d been saving it. On social media, you press the wrong button and… Thirty minutes later I missed four calls and I’m like, ‘That’s weird.’ But it was a good moment. I was only going to wait five or six more days [to share].” 
 
 But the slip-up doesn’t have her stressing about future social media posts. “Every week I just take a picture and save it and I’ve been so good about it and this was the one time I slipped, but it’s okay,” she said. 
 
 One week ago, the mother-to-be captioned a mirror selfie with her baby bump clearly visible underneath a custom yellow La Blanca Anniversary suit. “20 weeks,” she announced. 
 
 Later that same day, Williams’ rep confirmed to PEOPLE that she and her fiancé, Reddit co-founder Alexis Ohanian, will welcome their first child in the fall. “I’m happy to confirm Serena is expecting a baby this fall,” the rep shared.

 And just days after the baby news, the sports star posted a moving love note to her unborn baby. 
 
 Also at the Ted Talks event, Williams opened up her career plans post-baby. 
 
 “Roger Federer is older than me and he’s still winning everything,” she said about getting back in championship caliber shape. 
 
 “My baby’s going to be in the stands, hopefully cheering for me,” Williams gushed. ||||| Serena Williams is just like us, well, sorta. 
 
 The tennis legend admitted during her Ted Talk with Gayle King that she didn't mean for her pregnancy announcement photo to hit social media—but accidents happen! 
 
 "I asked you about that picture and you said nobody was supposed to see that picture. What do you mean?" King asked. 
 
 "Well, actually it was an accident. I was on vacation just taking some time for myself and I have this thing where I've been checking my status and taking pictures every week to see how far along I'm going," the pregnant star explained. 
 
 "I didn't tell a lot of people to be quite honest and I'd been saving it. And you know how social media is when you press the wrong button…and…" 
 
 King interjected, "There it was!" ||||| She’s a mom! Serena Williams has welcomed her first child with her fiancé, Reddit cofounder Alexis Ohanian, a source close to the tennis champ confirms to Us Weekly. 
 
 Williams, 35, gave birth to a baby girl at a hospital in Palm Beach, Florida, on Friday, September 1, the source tells Us. 
 
 As previously reported, Williams accidentally announced her pregnancy in a Snapchat photo on April 19. She posted a selfie that showed off her tiny baby bump, writing that she was “20 weeks” pregnant. 
 
 “On social media you press the wrong button and … 30 minutes later, I missed 4 calls and I’m like, ‘That’s weird,'” she explained to Gayle King during a TED conference in Vancouver days later.

 Following the announcement, Williams shared several more baby bump pictures on social media and opened up about becoming a mom. She also graced the August 2017 cover of Vanity Fair, stripping down to just a thong. 
 
 “I don’t know what to do with a baby,” she told the magazine. “I have nothing … I’ve done absolutely nothing for the baby room.” 
 
 The athlete learned that she was expecting shortly before winning the Australian Open in January. She was so shocked that she took six pregnancy tests. “[I] did a double take and my heart dropped,” she told Vanity Fair. “Like literally, it dropped.”

– Some thought Serena Williams was being coy when she posted the image last week that announced her pregnancy to the world, then soon after deleted it. But it turns out the tennis star had simply never meant for the picture to go public at all, People reports. The tennis star sat down Tuesday with Gayle King at the TED conference in Vancouver, BC, and revealed, as E! Online puts it, that she's "just like us, well, sorta" when it comes to messing up on social media. "It was an accident," Williams confessed about the baby bump reveal now seen 'round the world. She explained how she's been regularly taking pictures of her pregnancy's progress and saving it for herself, except this time around she hit "Send" instead of "Save." "You press the wrong button and…," Serena explained. Williams isn't taking the goof-up too hard, though, noting that she'd planned on sharing the big news in "five or six more days" anyway. (Williams' note to her unborn baby.)
