"People are going to think that's a joke," Brie Bella, 36, told People. "We are both shocked. People are going to think we planned it, but you can't really plan pregnancy!"
Brie Bella is expecting her second child with her husband, 38-year-old WWE professional wrestler Daniel Bryan, while Nikki Bella is expecting her first child with her fiancé, 37-year-old professional dancer Artem Chigvintsev, USA Today reported.
"Someone told us today, they're like, 'Wow, you guys are only a week and a half apart? It's like you guys are having twins, it's just the twins decided to grow in different wombs,'" Brie Bella told People. "I was like, 'whoa.'"
In an Instagram post, Brie Bella added that "never in a million years" did she think she and her twin sister would be pregnant at the same time.
She told People that she and her husband stopped trying to have a second child after having trouble getting pregnant in the months after Birdie was born.
“My husband and I were trying for seven or eight months," she said. "But then I felt in my heart it was a sign from God, like, ‘You guys are good with one,’ so we stopped trying."
She said she learned she was pregnant during a trip to France to meet her Chigvintsev's family.
"I felt a little off," she told People. "I was irritated and uncomfortable in my body. When we got home, I took a test two days before Thanksgiving, and when I saw the positive sign, I was like, 'Oh (expletive)!'"
Nikki Bella, 36, said she and Chigvintsev weren't trying for a baby when she learned she was pregnant.
"I was in yoga, and I kept getting this feeling that you need to take a pregnancy test, but I wasn't even late yet," she told People. "And so I'm like, 'Why do I keep having this feeling? Am I getting twin vibes from her? Because she just told me she's pregnant?'"
Nikki Bella announced earlier this year that she and Chigvintsev got engaged in November. The couple met on the set of "Dancing With the Stars" in 2017 and began in 2019 to date after Nikki Bella split from her ex-beau, actor and professional wrestler John Cena, E! News reported.
"Even though I feel really sick… (I) can't believe I'm going to be a mom soon," Nikki Bella told People. "It's something I've dreamed of my whole life."
