The reality star was filming scenes for tonight's episode of TOWIE in her pal Danielle Armstrong's clothing boutique, and opted for a very discreet all-black ensemble for the occasion.
Clearly not wanting to stand out too much, Billie covered up in a black jumper dress complete with a high polo neck design, teamed with opaque tights for added warmth.
The mother-of-one added a pair of leather Chelsea boots while completing her look with a black waterfall jacket worn on top of her knitted frock. We can't help feeling her polo neck and jacket ensemble boasted a bit of an Andy Warhol vibe!
Adding a slight touch of colour to her neutral getup, Billie wore a double coin gold necklace while dabbing a hint of peachy nude lipstick on her pout and amping up the drama with smoky eyeshadow and fluttery false lashes.
Her hair was very different too - while we usually spot Billie with her platinum locks styled in bouncy, tumbling waves, this time she swept her barnet back into a fuss-free low ponytail.
This is certainly a different look for the starlet, but she always looks fab no matter what she wears!
