Jo Miller says her daughter is innocent

Sienna Miller’s mum has defended her daughter over her controversial relationship with Balthazar Getty.

Jo Miller, who met the Brothers And Sisters actor over lunch in LA this month, insists Sienna has done no wrong.

‘You can’t understand how a woman seeing a man who has been separated from his wife for months can cause such a scandal,’ she says.

‘It’s awful, I can’t tell you. You wonder when it’s all going to stop.’

Balthazar, 33, announced he’d split from wife Rosetta, 38, last month.

Sienna, 26, has been widely criticised in the media but some columnists think she’s been treated unfairly.

‘Thank goodness some people are seeing the hypocrisy of it all,’ she tells the Daily Express.

‘I know it makes Sienna pleased to read these [positive] things.

‘It means a lot to her when there’s so much negativity and criticism around.’
