It turns out Katy Perry - who she is expecting with her fiancé Orlando Bloom - has an adorable nickname for her unborn child: 'Kicky Perry'.

The Roar hitmaker said during a radio interview: "I am waddling like a duck! I'm breathing heavily, I'm a full-on mouth-breather. And um yeah, it's loud and obnoxious and, oh my God, I just eat so much flavoured ice! It's like put all the ice in my mouth, right now!

"I call her Kicky Perry sometimes. I love a pun but I'm really active right now and, you know, my doctors are like, 'Stay active, you're good to go, girl!' And so I've been dancing, I've been singing a lot."

Earlier this year, Katy shared more about her unborn daughter with a hilarious update on her pregnancy.

The Roar hitmaker took to Instagram to share a sonogram of her unborn daughter and noticed something rather funny: her baby girl appeared to be pulling her middle finger at her mum.

"When your unborn daughter gives you a middle finger from the womb you know you’re in for it," Katy joked alongside the video of the unborn baby’s sonogram.

"Just like her mama,” Katy’s famous friend Rita Ora wrote in the comments of the clip.

Meanwhile, the 35-year-old singer is grateful Orlando - who also has Flynn, nine, with his ex-wife Miranda Kerr - has parenting experience, especially when they went baby shopping the other day.

She added: "The good thing is that he has a kid that's nine. And he's been through it. So when we were going to pick out strollers, he knew exactly the stroller. And like, some of the strollers are very chic, they've got leather handles and blah, blah, blah. And I was like really drawn to them right? And he's like, 'No, let me show you what the stroller is.

"It's this one that you pick up in the middle and it collapses and it's like, 'Bang, bang', it's like an umbrella. I was like, 'Oh my God, I'm so grateful that you know this, 'cause I would have gotten some, you know, large hunky thing' and that is avoidable because he's already had a test run so, I'm grateful for that. It was very cute, like he was a famous person who's like, 'Here's how you do it, you just pick it up from the middle and you just go 'Wham.' I'm like, 'I'm so turned on right now!'"
