In fact, we think Billie, 24, is looking even better than ever as her pregnancy gets well under way - now where's the justice in that?!
Chatting to Reveal's Associate Editor, Wendy Rigg, on our glamorous fashion shoot, Billie said:
"I haven't stopped wearing the things I love. Sequins, leopard print, bright colour and bling... I don't see why you should suddenly dress in a different way, just because you are pregnant. I don't think you should hide the bump - it's something to be celebrated!"
"I haven't bought loads of maternity wear. My bump's been quite small, so I have got away with wearing things that I already have. The only thing I did buy was a pair of stretch jeans. I'm still wearing bodycon dresses."
"When I'm not working I'm in comfy sweat tops and trackie bottoms – and my Jimmy Choo trainers."
(Reveal can confirm these are not your average trainers - Billie's are silver, glittery and wedge-heeled!)
"As far as maternity wear goes, I like Isabella Oliver dresses – they are well-cut and really comfortable as well as glamorous."
"I should have done a maternity line myself, but I decided to concentrate on babywear instead."
(BIllie's range of baby and childrenswear, Jam Kidswear, is available to buy from http://jam-kidswear.myshopify.com)
And Billie's not letting up on her social engagements, either.
"I still wear heels when I'm filming or out, but I've always got flip-flops in my bag. I can only do heels for about an hour, and I don't really feel like dancing all night in clubs right now."
