...and we know where you can nab her outfit from!
Like Kim Kardashian, Billie has scooped yummy mummy status thanks to her overflowing wardrobe and yesterday she opted for this stunning pinstripe two-piece that boasted a ruffle-adorned bandeau top and a co-ordinating maxi skirt with thigh-high splits.
Billie showed off her gorgeous glow in the monochrome number but you'd be a fool to think it cost her an arm and a leg.
The mum-of-one - who usually takes to Instagram to share the deets of her stunning outfits - was too busy soaking up the sun to spill, but because we're total style magpies here at Reveal.co.uk we know that the look hails from her very own clothing collection with In The Style.
And it won't break the bank at £29.99 - wahoo!
Billie put an ultra-glamorous twist on her sharp co-ords with a striking red clutch and pillar box red smackers but she opted for black strappy sandals to avoid being too matchy-matchy. Nailed it, right?
The reality star joined the likes of Chloe Sims, Kate Wright and Lydia Bright for a night out on the tiles but it's safe to say she won best dressed.
