Pint-sized pop star Kylie Minogue had to use a car booster seat for her latest screen role.

The Australian singer, who is just five-feet (152 centimetres) tall, needed a helping hand when she was filming for Nick Cave's documentary 20,000 Days on Earth, in which Minogue has a small cameo.

She was shooting a scene in which she sits in the back of a car while Cave is driving, but Minogue is so small she could not be seen on camera and had to use a booster seat to lift her up.

It is not the first time the diminutive singer has needed some height help - whilst appearing on Bbc talent show The Voice in January (14), she used a set of steps to help her into her spinning chair and stop her legs from dangling down.
