Jessica went to the bash as Beauty and the Beast's lead character Belle and sparkled in a yellow corset and matching net tutu skirt.
The reality star teamed her outfit with a pair of white suspenders, matching lace gloves and a pair of white heels covered in rhinestones.
Jessica topped off her look with the ultimate Disney princess accessory - a tiara!
Sam threw her fancy dress party to mark both the New Year and her birthday and she decided to go as Minnie Mouse - in an incredible pair of shoes!
Sharing a picture of herself on Twitter, Jessica tweeted: "Loved being Belle tonight for my @samanthafaiers birthday love you loads Minnie."
Following her bash, Sam took to the social networking site to thank her guests for going.
She said: "Had the most amazing party with all my family & friends so blessed ... Xxx"
