Ioni James is going to be a big sister!

“Your attention please! @ioniconran has a very important announcement to make!! #babyconran2,” the supermodel captioned the footage in which Ioni James happily yells: “There’s a baby in Mommy’s tummy!”

In the clip, the former The Face judge cradled her baby bump and wore a black off-the-shoulder gown as her little girl popped out from behind her garment, also wearing a coordinated black dress.

In November 2016, Rocha told PEOPLE that she and Conran were not quite ready for baby number two.

“It’s so much fun being with her and learning what life is with one at the time,” said Rocha of her little girl. “I couldn’t even think of an extra, I don’t know how to even love something else right now because I love her so much. One day maybe!”

The mother-to-be proudly celebrated Ioni James’ runway debut in Paris for a Bonpoint fashion show recently as the toddler proved she was following quite literally in her mom’s fashionable footsteps.

Though Ioni James’ interests are clearly fashion-oriented, her mom didn’t always think it would be that way. In February 2016, Rocha told PEOPLE “I don’t think so” when asked if her daughter would become a model someday.

“You never want to do what your mom does,” she explained. “I keep saying she’s gonna be some sort of scientist. Something crazy where I just couldn’t help her in her maths or reading skills.”
