It's been yet another successful and popular run, yet series six of The Only Way Is Essex is almost over.

The cast were filming the finale yesterday and on Saturday were spotted shooting scenes for Lucy Mecklenburgh's 21st birthday party.

Despite having just made up with the brunette, sisters Sam and Billie Faiers did their best to try and out do the birthday girl by turning up in glamorous floor-length dresses.

Billie opted for a flowing teal number that luckily didn't show off too much cleavage and featured a patterned neckline.

She teamed the dress with gold shoes and a simple matching bracelet as she arrived at Lucy's party at Sugar Hut.

The blonde wore her hair up and flashed a huge smile for the cameras as she made her way inside.

Close behind her way her sister Sam, who did decide to show off her chest.

The Minnie's Boutique owner highlighted her slender figure in a lilac gown that featured a jewelled top and cutaway sides as well as a very low V-neck.

Sam had clearly had extensions put in as her blonde hair was looking much longer, and as she arrived hand-in-hand with her boyfriend Joey Essex, she also had a huge grin on her face.

Joey looked rather dapper in a pair of grey checked skinny suit trousers, a smart white shirt and a dark blazer.

Someone else who opted to wear grey was Tom Pearce, who arrived with a member of the crew.

Another couple who made somewhat of an entrance was Gemma Collins and James 'Arg' Argent.

The pair were seen having a heart-to-heart outside and had worn matching black outfits.

While Gemma looked glamorous in a floor-length black number, Arg got it very wrong in a shiny suit and a matching shirt.

Following the filming session, the group were seen piling into a hummer limo which clearly had something to do with the prom theme of Lucy's party.

The reality TV star will celebrate her 21st birthday on August 24.
