Billie has been busy showing off her growing tummy in a chic navy dress, and we think she looks simply glowing.
The short frock is not actually meant to be maternity wear, although we think it hugs Billie's blooming bump perfectly.
Billie shared a picture of herself wearing the navy number with fans on Instagram, telling them: "Love this navy dress available from @minniesboutique #babybump #casual #comfy."
Last week, Billie returned from a holiday in Dubai having spent time relaxing and soaking up the sun with her fiancé Greg Shepherd, her sister Sam and the girls' mum.
She's definitely still got that sun-kissed glow!
While on holiday, the gang shared several pictures with fans back home and Billie showed off her bare baby bump in an array of pretty bikinis.
Billie and Greg are expecting a baby girl this summer.
