Miley Cyrus' MTV Video Music Awards performance has been defended by its creative director.

Diane Martel - the woman behind the videos for 'We Can't Stop' and Robin Thicke's 'Blurred Lines' - has insisted she fully supported the former 'Hannah Montana' star ''being over the top'' with her suggestive use of a foam finger.

The performance - which saw her grind and perform a 'twerking' routine with Robin whilst dressed in a flesh coloured, latex bikini - has had its critics, but its director saw no problem.

She told MTV News: ''Miley had ideas about how she wanted to perform; she was excited to play it mega-campy style.

''For 'Blurred Lines' I decided to use the [foam] finger and she took it and ran with it. She's into being over the top right now and I'm right there with her.''

Diane also blasted people who have criticised Miley for sticking her ''tongue out'' - suggesting a big ''generation gap'' - and insisted people should have more important things to worry about.

She added: ''For the geriatric crew, the tongue out is not sexual. It's selfie code. It's mocking 'pretty.'

''It's not for your gaze. It's for a young audience's gaze. There seems to be an enormous generation gap ... I am shocked by their shock.

''I think there is other news we should be focusing on ... Syria? Egypt? ... At the heart of this noise, you have a young lady playing with a performance.''
