Tulisa went hell for leather in a patent dress with a sheer top section, accesorised with towering silver platforms. The modern look was a contrast to Jade and Ella's outfits – both girls chose dresses that had a distinct Twenties feel.
Sixteen-year-old Ella stepped out in a lacy dress with a see-through top section and feathered hem, while 25-year-old single mum Jade wore a delicate floor-length creation with sheer sections and lace details throughout.
Rounding off the group, Last Night (Beer Fear) singer Lucy, 20, rocked her own distinctive style, her hair slicked back into a distinctive quiff and wearing a suit to the red carpet event. Meanwhile the boys were all on dapper form in Bond-worthy tuxedos and suits. Rylan Clark, James Arthur and Jahmene Douglas looked thrilled to be at the 007 unveiling – which took place in London in the presence of royal guests the Duchess of Cornwall and Prince Charles.
Gary Barlow's remaining acts Kye Sones and Christopher Malone were also in attendance, as were Louis Walsh's groups.
Union J and District3 – who wore navy and black suits – both looked to be enjoying their new found fame as they arrived at the Royal Albert Hall bash.
The up-and-coming stars were joined on the red carpet by X Factor success story JLS – who have gone on to achieve massive success after coming second in the 2008 season of the show behind winner Alexandra Burke.
Aston Merrygold, Oritsé Williams, J.B. Gill and Marvin Humes have scored five UK number ones and have sold three million records worldwide in the last four years since their time on the ITV1 programme.
The new contestants were clearly excited to bein the presence of stars like 007 himself Daniel Craig, Bond Girl Naomi Harris and Dame Judi Dench, who plays M.
Essex boy Rylan – who has divided fans with his flamboyant performances - upload a picture of himself and his best friend from the programme, Lucy, as they took to seats ahead of the screening.
The 23-year-old tweeted: "Watch out 007 #TeamSprylan are on the loose x"
Lucy and Rylan quickly bonded while filming the live shows. But they hit headlines when they were asked to leave the Corinthia hotel where the rest of the contestants are staying and sent to cheaper accommodation in Wembley after upsetting hotel staff with their behaviour following a drunken night out.
Rylan, who has celebrity fans in the form of Robbie Williams and Katie Price, apologised for his behaviour on Saturday night's club classics show, while Tulisa defended Lucy saying she had had a difficult time after the death of her grandmother.
"Lucy had a pretty tough week so everyone should really give her a bit of a break - everyone reacts in different ways. She's a young girl, she went out and had a bit of fun," said her mentor.
