Beyonce Knowles models her new mum bun as she carries baby Blue

Beyoncé Knowles took Blue Ivy out shopping in New York - and showed off a mamalicious new hairstyle at the same time!

Celebrity hairdresser Desmond Murray tells Now Online:'As a superstar and new mum, Beyoncé's opted for maximum impact but minimum effort.

'She'shad lightweight syntheticextensions in coffee, chocolate and honey tones, to complement her skin, micro-plaited into her natural hair in ultra-fine sections. It's a look that she can wear either up or down.'

On the downside, Desmond says it takes around six hours to achieve these braids. The good news is it only takes a minute to whip up into this mamalicious bun.

'Just tip your head upside down, twist it into a bun and grip into place with massive pins,' he says.

For an appointment with Desmond at Atherton Cox 18 New Cavendish Street, London W1G 8UR, call 020-7487 4048.
