She stars as the pretty and studious Gwen Stacey who plays it safe when it comes to her attire.

But Emma Stone was a far cry from her on-screen character tonight as she arrived at The Amazing Spider-Man premiere in London in a very plunging jumpsuit.

The 23-year-old actress posed for the cameras on the red carpet outside the Odeon Leicester Square in a black and sparkling Elie Saab outfit which was in danger of revealing more than she might have wanted.

But speaking to Mail Online outside the event she said she made sure she didn't suffer a wardrobe malfunction while walking the red carpet by smoothing the top half down.

And she seemed pretty confident in the daring outfit as she beamed for the flashbulbs as she stopped and talked to fans outside.

And her boyfriend and co-star Andrew Garfield could not tear his eyes away from her as they posed together for photos inside the cinema with their co-star Rhy Ifans.

Stone plays Andrew's love interest Gwen Stacy in the film, picking up the role previously played by Bryce Dallas Howard.

Emma, who met Andrew on the film, avoided talking about him but told Mail Online that it was 'totally surreal' and strange people were talking about her style as she uses a stylist.

She said to prepare for her role she 'went on the message boards which made me start to panic' but added that working with Andrew and Ifans 'was pretty fantastic'.

She made her way inside while Andrew made one fan's day as he knelt down to shake hands with eight-year-old Uzayr Haider.

Andrew, who plays the web-slinging hero, arrived looking very dapper in a black suit and tie.

He told Mail Online: 'Doing the premiere in London is so much more special and so much more personal. I have walked through Leicester square so many times inebriated.'

He added that he thought fans would be foolish to think he was a heartthrob but said it was 'not too bad' but when asked how Emma felt about his new status, he said: 'Well, I don't know about that you will have to ask her.'
