Sir Paul McCartney has urged critics to lay off Miley Cyrus over her raunchy routines, insisting: "We've seen worse than that."

The Beatles icon made a special effort to check out the former Hannah Montana star's controversial performance with Robin Thicke at the MTV Video Music Awards in August (13) and also viewed her promo for single Wrecking Ball, in which she is naked save for a pair of boots.

Both incidents have sparked a wave of accusations that the former child star has gone too far in sexualising her image, but MCCartney is baffled and believes Cyrus is being treated unfairly.

He tells Sky News, "You know what, I don't think it was explicit at all. You couldn't see anything! I watched it just as an experiment, to check. But obviously you look at it and you go, 'What's everyone shouting about?'. I thought it was only mildly shocking. I know she is dancing with Robin Thicke at the awards - so what? Come on! We've seen worse than that."
