Kylie Minogue has spoken of her concerns that she may be too small to fill her chair as a judge on The Voice.

The Australian star is well known for her short stature, standing at just over 5ft tall and before stepping into the role of mentor she joked that she would need a “booster seat”.

“I thought it could look pretty comical, me being in that huge chair!" she joked

"In the initial meeting I had joked, ''Maybe I'll need a booster seat!'' That was not employed, but the box [a small footstool] makes me way more comfortable. Although the guys' feet don't touch the floor either! The chairs are massive and they have to be because if you're leaning a certain way, you might catch a peripheral glimpse of something you're not meant to see."

Kylie’s younger sister Dannii was the winning judge on last year’s Australian version of The Voice so has apparently been the perfect person to give her advice about donning the role.
