Before entering the Celebrity Big Brother house, Sam threw a fun-filled birthday bash last Wednesday evening (1 January) and urged all of her guests to wear costumes from their favourite Disney films.
Ferne chose to dress up as Ariel from The Little Mermaid and donned an eye-catching, glittery green fishtail, which flattered her curves.
She teamed her tail with a seashell bustier, red hair and plenty of pearls around her neck, while also making sure to go all out with glittery eye make-up and purple lipstick.
But not only did Ferne finally let fans see her Disney outfit in its entirety, she also posted Instagram snaps with birthday girl Sam and BFF Billie Faiers earlier this week, so that we can now check out their cute costumes too!
Sam - who turned 23 years old on the night - proved her love for Minnie Mouse by wearing a spotty red and white cropped top with puffball sleeves and a matching skirt that featured a large black sequin bow.
She also wore knee-high black socks, red peep toe heels and a pair of mouse ears.
Her older sister Billie - who confirmed that she is pregnant with her first child this month - opted for a Tinkerbell costume and got dolled up in a neon green minidress and a pair of wings.
Aww - we can't get enough of these photos!
Beside the picture with Sam and another pal dressed as a Dalmatian, Ferne wrote: "Love my friends".
Both Ferne and Billie have been Sam's biggest supporters since she entered the Celebrity Big Brother house last Friday (3 January).
As well as watching and commenting on the show's antics every night on their own Twitter pages, the twosome have also been making sure to keep Sam's Twitter page updated with words of encouragement and support from her fans.
Last night (7 January), Ferne tweeted: "Need to see some more of our girl...trust me when I say there's a lot more to come from @SamanthaFaiers".
We bet there is!
