It's a chorus chanted by the mothers of teenage daughters the length of the country: ‘You can’t wear that skirt... it’s far too short.’

But in the Jagger household they do things slightly differently – with the youngsters wading in to protect their mother’s dignity.

In her first interview, Georgia Jagger, the youngest daughter of Mick Jagger and Jerry Hall, has revealed how she confiscated all her mother’s miniskirts when Jerry turned 50.

Sixteen-year-old Georgia says: ‘I did take all her miniskirts. I told her one night that her skirt was too short – she came down the stairs and I was like, “God, Mum, you are 50.”’

Texan model Jerry – who once famously said she’d wear bikinis until she was 80 – hit her half-century two years ago and seems to have taken her daughter’s advice about skirts.

She put her minis up for auction earlier this year, alongside the dress she wore when she married Mick in Bali in 1990.

They split in 1999, and Jagger had the marriage annulled on the grounds that it was not valid under English or Indonesian law.

Georgia’s interview, in The Mail on Sunday’s You magazine today, gives a revealing insight into the Jagger family.

She says 65-year-old Mick is ‘just Dad’; the most important lessons her mother taught her are to ‘be nice, and on time’ and that her 24-year-old sister Lizzie is her best friend.

Of her father, she says: ‘Actually he’s not as cool as you’d think he’d be. He’s fun but everyone thinks he would just want to party all the time but, well, he’s just Dad. He worries like most dads do.’

She likes his music and says she has ‘lots’ of Rolling Stones songs on her iPod. ‘Sympathy For The Devil is my favourite track,’ she says.

Georgia, who also has two brothers – James, 22, and Gabriel, 11 – adds: ‘Lizzie is my absolute best friend. The only thing we argue over is clothes – but all sisters do that.’

Georgia, who has her father’s lips, could follow her mother on to the catwalk.

She was signed up by agency Elite Models, which represents her mother and older sister, when she turned 16 this year.

But she won’t be tempted into cosmetic surgery to help her career along.

She says: ‘I wouldn’t even have braces on my teeth. This idea that everyone should conform and be perfect is ridiculous.

‘I like the fact that I have good old-fashioned British teeth with a big gap. Who wants those gleaming white cosmetically enhanced American teeth?’

Georgia – one of seven children Mick has fathered with four women – is studying art, photography and sociology at A-level and her ambition is to be a photographer and fashion designer.
