The bubbly TOWIE favourite has been looking a-mazing throughout her pregnancy whether she's wearing slinky dresses, super high heels or cosy jumpers, and today was no different.
Of course, it wasn't about style today, it was about charity and education, as Billie, 24, joined fellow pregnant women in Primrose Hill, London, to lend her support to the British Heart Foundation's latest campaign, Fight For Every Heartbeat.
It hopes to raise awareness of inherited heart conditions.
Proudly wearing her campaign T-shirt – and flashing her baby bump – reality star Billie said: "It's fantastic to see so many pregnant women helping raise awareness of inherited heart conditions for the BHF. We need to do everything we can to raise money and invest in research which can dramatically help those living with inherited heart condition."
The new campaign has a social media aspect, encouraging pregnant women to upload photos of their baby bump online with the hashtag #BareYourBump.
Billie, who is seven months pregnant, showcased her blossoming bump in a white vest and the campaign T-shirt, while the women around her proudly flaunted their bare bumps.
The new campaign wants to educate people about the fact there is a 50:50 chance someone with an inherited heart condition could pass it on to an unborn child. It also hopes to encourage further research in the field.

Billie, who is engaged to long-time boyfriend Greg Shepherd, announced her pregnancy in January 2014, making her the first female TOWIE star to start a family. She's already revealed it will be a baby girl.
