Supermodel Miranda Kerr is staying mum on the sex of her third baby, her second with husband Evan Spiegel.
In an interview with Marie Claire, the 36-year-old shared that while she and the Snapchat CEO know whether they've having a boy or a girl, the pair are choosing to keep it a secret.
"Yes, we know the sex and we have names," she said. "But it's nice to keep a little to yourself."
Kerr previously described her husband of two years as "Mr Private".
"I have to respect that," she said.
Kerr, who is mum to Flynn, eight, with ex-husband Orlando Bloom and one-year-old Hart, also admitted that her third pregnancy has been the hardest.
"There was a lot of morning sickness in the beginning," she said. While her pregnancy with Flynn was "very smooth sailing", Kerr explained that she had a little morning sickness while pregnant with Hart.
This time, however, she's been quite unwell, even spending time on bedrest.
"With this little one I've had terrible morning sickness," the model mum said. "But I'm feeling good now and it's not long to go now, which is exciting."
Both Flynn and Hart are also eagerly awaiting the arrival of their younger sibling.
"Flynn is madly in love with Hart," Kerr said. "He really wanted a little baby brother so much. There hasn't been any jealousy or anything. It's been very sweet. And when Flynn walks in the room, Hart lights up like a light bulb."
