Georgia May Jagger finds exercise "boring".
The 24-year-old model - who signed to Independent Models in 2008 - has admitted she doesn't follow the stereotype that all catwalk icons go to the gym, and has revealed she doesn't exercise because she doesn't get any enjoyment from working up a sweat and has been "bad" at athletics ever since she was a child.
Speaking to ES Magazine about how she maintains her slender frame, Georgia - who has been the longstanding face of the beauty brand Rimmel and has modelled for luxury fashion houses Chanel, Miu Miu and Versace - said: "I was always a bit bad with sports and stuff as a kid. I think people assume that all models are working out in the gym but I'm really not that kind of person. I find it quite boring."
However, Georgia - who is the daughter of Rolling Stones' lead singer Mick Jagger and his ex-wife Jerry Hall - believes the secret behind her toned arms is carrying around a hefty suitcase.
She explained: "I carry my suitcase around a lot, though. I drag it up and down."
Although the blonde beauty tends to skip fitness sessions, she has revealed she follows a healthy eating regime and regularly drinks home-made juices, which she prefers to have instead of thick smoothies.
Speaking about her eating habits, she said: "I'm trying to eat less meat now.
"I don't like smoothies, so I have a cold-pressed juicer. I don't like it to be very thick and with bits. But I'll do a green juice; cucumber, apple and spinach or something. Sounds horrible but it's actually quite nice. You've got to put some apples or pears in it - you can't just put vegetables."
