Georgia May Jagger threw a tantrum to get Dame Vivienne Westwood to design a dress for her.

The model - who is the daughter of Sir Mick Jagger and Jerry Hall - says her family's legacy means she rubbed shoulders with the 71-year-old fashion legend from a young age, but she didn't used to be fan of the designer because Vivienne hadn't made her a custom-made dress when she made a gown for the other females in her household.

Georgia said: ''I was about seven and having a bit of a diva stage. Vivienne made these dresses for Leah Wood's 21st birthday, for my sister [actress-and-model Lizzy] and my mum. I helped them all get ready and was really upset that I couldn't go.

''I was really unimpressed. The next time I saw Vivienne, I said, 'I don't think you're a real designer, because if you were a real designer, you'd have made all the ladies in the family dresses...' ''

Although the gap-toothed blonde has successful campaigns for Rimmel and Hudson jeans and is now the face of Vivienne's new jewellery line, she insists she is far from a diva these days and actually leads a very low-maintenance lifestyle.

Georgia laughed in an interview with Grazia magazine: ''People think I wake up every day and have my make-up done. Actually, I don't really know what people think. That someone wakes me up with, like, an egg-white omelette and I get on the treadmill at 10.30, my stylist comes in and picks me an outfit to wear to the shops or the park? It's really not like that.''
