The reality star - who is currently soaking up the rays in Dubai - has taken to Instagram to show us what she's been getting up to and our eyes nearly popped out of our head when we spotted her in this in-your-face orange two-piece.
PHWOAR is the word we're looking for here!
Billie rivalled co-star Kate in the itsy bitsy waist stakes and showed off her absolutely stunning hourglass shape in the bright orange, curve containing bikini that boasted halter neck straps and fierce gilt chain detail to boot.
But Bills has been wearing her In The Style swimwear collection to death lately, and chose to switch it up in the two-piece which she revealed is from celebrity favourite, Bahimi.
The best part? It'll only set you back £35.
No, scrap that. The real best part is that the tie-up bikini top comes in loads of different cup sizes so you won't have to worry about re-adjusting after your morning swim. Hurrah!
Billie matched her short and neat talons to the bikini and proved that she is a natural beauty as she gave all traces of make-up the elbow.
Er, can she get any hotter?
