Sibling bonding! Nikki Bella is relying on her twin sister, Brie Bella, more than ever relationship after they announced they’re both pregnant on January 29, a source exclusively tells Life & Style.

“Nikki and Brie are close, but the fact that they’re both pregnant at the same time has bonded them like never before,” says the insider. “Brie’s done it before so Nikki is getting the benefit of having her best friend and sister to lean on for support and pregnancy advice.” Brie already shares 2-year-old daughter Birdie with husband Daniel Bryan, while Nikki is expecting her first child with fiancé Artem Chigvintsev.

The sisters, whose due dates are less than two weeks apart, couldn’t be more surprised they’re sharing this experience together. “@thebriebella, this life just wants you and I to be twinning at everything we do. LOL,” Nikki wrote on Instagram after revealing the exciting news. “And even though we were shocked, beyond shocked, here’s another journey that I am so grateful to God to have you by my side. You have already been the best teacher! And Bird, too. LOL making sure I drink a lot of water and telling me my belly is getting big. Goodness, I love her so!”

Brie is just as excited. “We are shocked like all of you!!!” the soon-to-be mom of two wrote on IG. “Never in a million years did I think @thenikkibella and I would be having pregnant bellies together!!!” Brie also divulged she wouldn’t be surprised if they give birth at the same time.

The brunette beauties have a lot to look forward to, including finding out the sex of their babies together. “Now comes the fun part, there’s already buzz that they want to do a twin gender reveal,” another insider previously told Life & Style exclusively. “Daniel and Nikki’s fiancé, Artem, who were just as shocked about the baby news as they were, are on board for a group baby reveal too. I hear they’re already planning something and they all agree that it has to be epic. Nikki and Brie are still pinching themselves.” How exciting!
