Amazing Spider-Man: Emma Stone sparkles in low-cut trouser suit, joins Andrew Garfield

It takes a pretty special girl to steal the show at a premiere in trousers - but Emma Stone was that girl as she hit The Amazing Spider-Man launch in London.

Hollywood actress Emma Stone joined on AND off screen boyfriend Andrew Garfield at the official premiere of The Amazing Spider-Man in London's Leicester Square.

And there was no long ball gown in sight.

'The Help' star Emma avoided the cliched long black dress as she hit the red carpet wearing a black wide-legged pair of trousers.

And she made sure that she had both girls and guys crushing on her as she teamed it with a sequined long-sleeved top which dipped down at the front to almost her naval.

She added a gold belt to show off her tiny waist - and had her golden blonde hair loose and down.

'The Social Network' star Andrew Garfield - who plays her romantic interested in the film and is also her man off camera - looked dapper in a navy suit and deep blue tie.

The pair, who have kept their relationship out of the media, avoided arriving together and didn't pose for pictures together on the red carpet.

Andrew Garfield recently revealed that he couldn't help falling for her while they were filming the movie.

The actor, who stars as Peter Parker and the webby hero, has admitted that it was between takes that he realised that his feelings were "different".

He told MTV News: "We got on really well as people, in between takes. That was the fun stuff. In between, we'd just mess around and I felt, 'Ah, this is different'.

"I wasn't really aware of what was happening in the screen test. She keeps you on your toes and that wakes you up. That was the beginning."
