Both girls went for full-on glittery make-up to top off their fabulous Tinkerbell and Ariel fancy dress outfits!
We're yet to see pictures of the birthday girl herself, but Billie, Ferne, Lucy Mecklenburgh and Jessica Wright were among the glamorous guests who hit Essex to celebrate Sam's 23rd birthday.
And while Jess looked super-sexy dressed as Belle from Beauty and the Beast, Billie chose Tinkerbell from Disney classic Peter Pan and Ferne went as Ariel from The Little Mermaid.
But what's a Disney outfit without plenty of glittery make-up? Rubbish if you're a The Only Way is Essex lady, that's for sure!
Billie wore a mixture of bright green shadow and glitter on her eyes, which was revealed on Twitter yesterday by friend and make-up artist, Makeup by Ashley.
This was the perfect choice for Billie's cute green Tinkerbell outfit and was topped off with her hair piled into an oversized bun and held together with a big satin bow in the same colour.
Meanwhile, Ferne McCann, whose look was also created by Makeup by Ashley, wore a stunning blend of bright blue and purple glitter on her eyes which literally screamed 'mermaid'!
And a cheeky little make-up trick was revealed by this shot of Ferne having her make-up applied below...
Yes, if you're wondering what those clever little cotton pads under Ferne's eyes are, let us fill you in...
They're called Shadow Shields, £7, sallyexpress.com and they're basically half-moon shaped pads you place under each eye to stop your eye make-up ruining the rest of your look.
You can also use them to create straight edges and winged shapes for eyeshadow, and to help you apply lipstick that looks as perfect as a pro's.
Pretty clever, huh? And essential if you're applying glitter on your eyes as that stuff gets everywhere!
And Christmas may be over, but if you fancy going a little glitter crazy like the TOWIE ladies, we're loving the MUA Luxe Glitter Palettes, £4 each, muastore.co.uk.
Four quid for 4 fabulously coloured glitter gels? Yes, please.
Now Sam, where are the pictures of YOUR outfit, hair and make-up? We're getting desperate now...
