Mollie King worries she might catch the pregnancy bug.

She joked: "I keep saying pregnancy is contagious and I'm going to catch it next! It's so nice for the girls, as we're like a big family anyway."

The girl band spent three months in Los Angeles filming their reality TV show 'Chasing The Saturdays' and Mollie admits she became strangely comfortable having every second of her life captured on camera.

She explained: "I remember thinking that I would never get used to having the cameras on me 24/7 but we became so close to the director, cameramen and crew.

"I'd watched shows like 'The Kardashians' and wondered how they could be so open on camera, but its easier when you feel like you're around friends. That's what makes for a good show, as you open up and stay true to who you are."

However, the bubbly blonde won't be setting up a permanent home in the US, despite now being loved-up with American music producer Jordan Omley.

Mollie told Britain's InStyle magazine: "My heart is in London. I'm proud to be British and will always consider it my home. I miss the skyline and fry-ups with friends at the weekend when I'm away. There's only so much Skype can deliver on."
