WWE twins Nikki and Brie Bella announce they're pregnant - with their baby due dates less than two weeks apart

Nikki and Brie Bella have announced they are both pregnant at the same time - and are due just a few weeks apart.

36-year-old WWE twins Nikki and Bella Brie, who are with Dancing With The Stars' Artem Chigvintsev and Daniel Bryan, respectively, retired from the sport in March last year.

Now, the pair have announced the exciting news that they're both pregnant.

Pre-empting people's reactions to the news, Brie told PEOPLE magazine: "Wait, twins being pregnant at the same time? People are going to think that’s a joke."

Before adding: "People are going to think we planned it, but you can’t really plan pregnancy!"

Brie already has a daughter named Birdie with husband Daniel, whom she married in 2014.

For Nikki, however, this marks her first child with partner Artem, whom she's been with since January last year.

The couple had been trying to conceive a baby for some time, Nikki explained: "[It was] a total surprise. 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."

She continued: "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.

"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?'"

Opening up about having the same symptoms, Brie added: "We have definitely felt better in our lives. It's actually crazy because we both have the same symptoms. So we've been super nauseous."

While the twins didn't reveal their exact due dates, they did state they were expecting around the same time.
