They are the first girl band to make it through to the X Factor semi-finals, so it's no wonder Little Mix might be slightly concerned about their standing after the show.

So in preparation for this weekend's live shows, the girls have been doing some self-promotion, with Jade Thirlwall leading the way this evening in a nifty pair of personalised tights.

The legwear featured the letters of the band name Little Mix scattered randomly over the sheer black net.

She was joined by her fellow Little Mix bandmates, Perrie Edwards, Jesy Nelson and Leigh-Anne Pinnock, as they posed for photographers at the Royal Film Performance of Hugo, a film directed by Martin Scorsese.

Having clearly embraced the cardinal rule of girl group dressing, the quartet co-ordinated beautifully in their monochrome numbers.

While Perrie opted for a pair of tight black leggings, white shirt and black leather jackets, Leigh-Anne went for a cute black and white dress with black boots and white socks.

And Jesy looked stunning in a pair of shimmery black trousers, white vest top and black blazer as the girls joined famous faces including the film's stars Sir Ben Kingsley and Chloe Moretz.

Kick-Ass star Chloe looked stunning in an all-black outfit as she posed up at the star-studded premiere with her 14-year-old English co-star Asa Butterfield.

The early 20th century period festive epic sees her play a young girl Isabel, a friend of the titular main character Hugo, played by Butterfield.

The youngster is an an orphan living a secret life in the walls of a Paris train station in the early 1930s, and he must repair a damaged automaton toy to discover a message from his dead father, who is played by Jude Law.

Much of the action takes place in the station, and Chloe said she could not believe the scale of the set that was made to bring it to life for the $170m budgeted flick.

She said: 'It was a full-scale train station. It was built in two studios placed side by side, which made it gigantic.

'And they built, to scale, an actual train station. It truly was one of the most magnificent things I’d ever seen. I walked in and saw it for the first time and thought, “It’s really happening.” It was beautiful.'

The screening of the film was also attended by director Scorcese, as well as Prince Charles and the Duchess of Cornwall.

The premiere, at the Odeon in Leicester Square, is the principal fundraising event of the Cinema and Television Benevolent Fund, the trade charity for the UK film and television industries.

Founded in 1924 the organisation offers practical and financial help to more than 1,000 people and their families every year who have been affected by illness, bereavement, accident or unemployment.

Former Countdown presenter Carol Vorderman was also present at the premiere, looking stylish in a black swing-style coat.

Hugo opens in cinemas in the UK on Friday.
