Kimberley Walsh has revealed she was nicknamed "duck bum" at school because of her voluptuous behind.
The Girls Aloud star said she has always been aware of her curves but has learnt to embrace them.
The singer admitted she felt pressure to be skinny when she was younger, but then Beyonce entered the spotlight and became her role model.
Kimberley explained: "I grew up thinking Kate Moss was the perfect woman but that was a totally unachievable body shape for me.
"Then along came Beyonce.
"We were exactly the same age and she looked amazing, so I started to dress like her and suddenly my shape made sense.
