Beyoncé's wigs 'worth $1 million'

A wig collection belonging to Beyoncé Knowles has been estimated to cost $1 million (£550,000).

According to In Touch, the singer has tailor-made hair-pieces for every occasion.

A friend told the magazine: "The majority of them are custom-made from real hair and she's probably got $1 million worth of stunning wigs.

"It's part of the reason why she always looks so gorgeous."

Knowles is said to donate her old wigs to a charity which helps cancer sufferers.

The 'Crazy In Love' singer was recently named the second highest-paid music act of the past 12 months, banking more than £40 million.
