Nikki Bella recruits niece Birdie to measure her growing baby bump as she & Brie continue journey

Nikki Bella recruits her niece Birdie to help measure her growing baby bump: ’19 weeks today!’

She and her twin sister Brie have been closely charting the progress of their concurrent pregnancies, as they are just about two weeks apart. 

First-time mom Nikki Bella took to Instagram once again on Thursday, with a video clip uploaded to her Story and feed showing her getting ready to measure her growing bump.

The 36-year-old former pro-wrestler had a little help, from none other than her niece Birdie Joe, the two-year-old daughter to Nikki’s sister Brie.

In the snippet, Nikki is seen in an understated ensemble consisting of a grey sports tank with the word ‘fearless’ on it, and black leggings.

Her black hair hangs down and loose as she handles the pink measuring tape and introduces her cute niece seated to one side, in a purple tutu.

‘So I brought my helper today, Birdie, to help measure my belly,’ Nikki tells the camera, as she caresses the top of Birdie’s head.

‘Do you want to help Dodo measure her belly?’ she asks Birdie, revealing the child’s pet name for her aunt.

‘Yeah,’ the tot replies coyly, laughing. She also instructs her aunt to do the actual measuring when Nikki asks her, ‘Do you want to do it, or should I?’

As Nikki wraps the tape around her waist, she exclaims, ‘Whoa, do you know that number, Birdie?’

All the littler girl can muster is a cute and childish shriek in response.

Written over Nikki’s Story entry, it says, ‘Bella Baby Watch: Nikki at 18 Weeks’ above another line which read: ‘Birdie helps measuring the bump!’

’19 weeks today!’ the caption concludes, charting her progress.

While this is the first child for Nikki and her fiance Artem Chigvintsev, her sister Brie is pregnant with her second, after giving birth to little Birdie.

While many have speculated that their concurrent pregnancies were pre-meditated and planned to coincide, the sisters have insisted it’s all entirely coincidental.
