Ciara And Russell Wilson Pregnant With Their Third Chil

American singer Ciara is pregnant.

The 37-year-old star has announced that she’s expecting her fourth child, and her third with her husband Russell Wilson.

Ciara posted a video to share the news on her Instagram: ““You look at me like that again, we make another kid… You my heart I’m your rib” [heart emojis] (sic)”

In the video, Ciara is seen posing in front of a pool, as she turns sideways to show off her baby bump.

A source told PEOPLE magazine: “Ciara has been working and travelling all through her pregnancy. She shot the ‘How We Roll’ video while pregnant. She was dancing on set all day long for a full day’s shoot.”

Ciara who already has Win, three, and Sienna, six, with Russell, as well as Future, nine, with rap star Future has impressed people around her with her energy levels over recent weeks.

The insider explained: “She’s one of those mothers who has energy throughout her whole pregnancy. She always calls her life organised chaos – but it’s organised chaos taking it up another notch.

“She loves being a mother so this is what she loves doing. This is what she has always wanted, and Russ too. They’ve always wanted a lot of kids.”

Earlier this month, meanwhile, Ciara revealed that she’s loving the challenge of raising three children.
