Coco Rocha and daughter Ioni

The 29-year-old supermodel posted a video on Instagram of herself standing in a nursery wearing a full-length, fitted, black evening dress and holding her stomach and standing next to her daughter Ioni Conran.

Two-year-old Ioni then jumps out from behind her and shouts: "Surprise! There's a baby in mummy's tummy!"

Mother and daughter then laugh and embrace.

Coco captioned the video: "Your attention please! @ioniconran has a very important announcement to make!! #babyconran2. (sic)"

The model and her husband, artist James Conran, have been married since 2010.

They announced their first pregnancy on Instagram with a video showing a CGI-version of Coco - complete with baby bump rotating like a doll inside a music box. Ioni was born on March 28th, 2015.

Coco told her followers at the time: "James and I are so proud to welcome into the world our healthy and beautiful baby girl, Ioni James Conran!"

Coco recently admitted she is a lot more selective about the modelling jobs she takes on now she is a mother.

She said: "Now that I'm a mom, when it comes to campaigns and editorials, I look at the bigger story. I ask if that's a good fit for the Coco brand, should I work with every editorial that comes my way, every brand. It's about pinpointing what's good ...

"I didn't want to be consumed by my career. Now we have a baby girl and that's what grounds me. I travel as much as I can with my family. My hair and make-up team are people that I absolutely love, who make me laugh. We're not curing cancer. We're going to do our jobs, doing it well, and realise we can have fun."
