Grabbing the limelight: Billie Faiers (L) upstaged her sister Sam at her 21st birthday party last night by wearing a plunging dress
They may be siblings but Sam Faiers would have been well within her rights to feel annoyed with her sister last night.
It seems that The Only Way Is Essex star was upstaged by her older sister Billie at her 21st birthday party last night.
Arriving at Orsett Hall in Essex, Sam posed for photos with Billie and their mother Sue Wells but no doubt all eyes were on sister Billie's ill-fitting dress.
The dress code for the party was obviously all out glamour, but Billie's strapless dress could barely contain her ample bosom.
While the birthday girl went for a more demure look in an all gold sequin dress by Pastiche Couture that draped the floor and highlighted her curves, her limelight-hogging sister squeezed herself into the black and white animal-print gown which she looked in danger of falling out of .

The pair posed with their youthful looking mother Sue who looked similarly stunning in a baby blue gown that featured diamante detail.
She looked more like one of her daughter's friends as she flashed her pearly white smile and showed off her trim figure.
The trio had obviously topped up their tans as they looked particularly bronzed and later that night they were seen enjoying some of the birthday entertainment.
Sam had managed to persuade X Factor hopeful Kitty Brucknell to perform at her party, and of course she showed off some flesh too.

But of course the other TV guests at the party were Sam's TOWIE cast members.
Posing for the cameras was couple Lucy Mecklenburgh and Mario Falcone, who certainly looked like they were getting in the party spirit.

The tailor finished off his look with a pair of gold star sunglasses and a brown cowboy hat as he pouted for the cameras.
