Are we right, or are we right?!
The reality beauty showed her support for friend and ex-The Only Way Is Essex co-star Amy Childs as she re-launched her beauty salon in Brentwood, and she proved that she can pull off the laid-back look just as well as high-chic.
Billie - who just lifted the lid on a Marbella-inspired swimwear collection with In The Style - showed off her sensational curves in a pair of high-waisted indigo jeans with splits at the knee and she drew attention to her wasp waist (HEL-LO, body envy) in this blue and white nautical T-shirt.
Bill stood tall in a pair of camel coloured ankle boots as she cradled cuter-than-cute daughter Nelly, and she dialled up the glam-factor behind a pair of tortoise shell-effect sunglasses.
The stunner was perfectly made up (can we just take a mo to appreciate that Rosie Huntington-Whiteley-esque contour?!) and rocked her perfect blonde locks in beach-y tousles.
The star joined former TOWIE co-stars Harry Derbidge, Pascal Craymer and male model Sam Reece (swit-swoo!) at the Brentwood bash - but it's safe to say she came out on top!
