"Thank you to @TheTanExpert for my #NYE @fakebakeunited #SprayTan," the gorgeous mum tweeted on Monday (29 December), along with this cheeky, 'I'm practically naked behind this towel' snap!
Billie, who just enjoyed her first Christmas with baby daughter, Nelly, rarely looks anything less than gorgeous, and after tanning up for her New Year's Eve celebrations, we look forward to seeing her chosen hair, make-up and outfit in a few days time.
In the meantime, we can all take inspiration from The Only Way is Essex star and add a little tan into our party beauty prep.
Billie was lucky enough to get her tan professionally applied by Maryam Eloise, celebrity spray tanner for Fake Bake and owner of ME Beauty salon in Gants Hill, Essex.
And there's still time for you ladies to do the same before 2015 is upon us... just 48 hours and counting!
If you'd rather save a few quid, however, and tan up at home, some of our favourite fakes include L'Oréal Paris Sublime Bronze Express Pro Self Tanning Dry Mist, £10.33, boots.com and former TOWIE lady Lauren Goodger's LW Tan Medium Self Tan Bronzing Mousse, £17.95, laurensway.com.
Just remember to give your skin a good exfoliation before applying your tan and smooth moisturiser over any dry patches like knees and elbows first.
Take your time to blend the product carefully all over your face and body and use a mitt if you really want a super-professional result.
Oh and NEVER tan up directly after waxing or you'll end up with dark pools of fake tan in all of those open pores. And, correct us if we're wrong, but dotty legs and short LBDs do not make for a good partying combo!
