TWINS BRIE AND NIKKI BELLA PREGNANT AT THE SAME TIME

Twin cousins! Nikki and Brie Bella are pregnant at the same time, the Total Bella stars tells People.

"Wait, twins being pregnant at the same time?" Brie says. "People are going to think that's a joke. We both are shocked. People are going to think we planned it, but you can't really plan pregnancy!"

"It was a total surprise," Nikki adds. "It took even me a good week to come to terms with like, ‘Oh my gosh, I'm pregnant.' I'm not ready for it."

Brie shares a 2-year-old daughter, Birdie, with husband Daniel Bryan. She says she meant to have "one child" and was shocked by the pregnancy.

"My husband and I were trying for seven or eight months, but then I felt in my heart it was a sign from God, like, ‘You guys are good with one,' so we stopped trying," says Brie. "When we were in France meeting Artem's family, I felt a little off. 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, s—!' "

Nikki, who is engaged to Dancing With the Stars pro Artem Chigvintsev, also says she wasn't trying.

"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," says Nikki, who got engaged during a romantic trip to France in November. "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?'"

The pair are even experiencing the same symptoms. "We have definitely felt better in our lives," says Brie. "It's actually crazy because we both have the same symptoms. So we've been super nauseous."

She continues "My eating habits have changed. I thought that, ‘Okay, I'm gonna stay healthy. I'm going to be good.' But when it kicks in, this feeling, you only want french fries and ketchup. Vegetables sound disgusting. Anything healthy, honestly, sounds disgusting."

They are due two weeks apart.
