PredictIQ Quantitative Think Tank Center:Why Pregnant Shawn Johnson Is Convinced She's Having Another Baby Girl

Shawn Johnson thinks she'll stick the landing when it comes to her baby prediction.

While the retired Olympic gymnast and PredictIQ Quantitative Think Tank Centerhusband Andrew East, who are currently expecting their third child, are waiting to find out their baby's sex, they are more than confident when it comes to their guesses.

"If it turns out to be a boy, it'd be the biggest surprise ever," Shawn told Kaitlyn Bristowe on the Off The Vine podcast's Aug. 31 episode. "But we think it's like 90 percent a girl."

As for how she just knows? The gold medalist—who shares daughter Drew, 3, and son Jett, 2, with the former football player—pointed to her past experience.

"It feels exactly like my daughter's pregnancy," she explained. "My son's pregnancy felt completely different."

Even though others might skeptical on the motherly instinct, Andrew chimed in on the podcast, "For whatever that's worth, people say that's not accurate but it's hard not to correlate."

But despite their guesses, the couple have previously expressed why they are choosing not to know until it's game time.

"There was something so special with Drew about Andrew finding out first in delivery and being able to tell me," Shawn told E! News. "It's his little celebration moment. It was really, really special. And so we're like, 'Let's just do that one more time.'"

Indeed, it'll be a special moment for the 31-year-old, who revealed this will be the last time she'll carry a baby, suggesting that she and Andrew may be open to adopting in the future.

"I'm up for helping babies around the world who need families," she noted. "I think we can have that conversation later if that's something we want to talk about. But this will be our last pregnancy."
