Victoria Beckham has got a ''secret wild side''.

According to the fashion designer's hairdresser Ken Paves, the 39-year-old star - who has sons Brooklyn, 13, Romeo, 10, Cruz, seven, and 16-month-old daughter Harper with husband David Beckham - has a great ''vibe'' about her which constantly sends her friends into raptures.

He said: ''I first met her and David in Rome when I was with Jennifer Lopez. We all got chatting at Tom Cruise and Katie Holmes's wedding and had a laugh. Victoria has got a secret wild side.

''She has this vibe that makes everyone around her laugh. When she moved to Los

Angeles [in 2007], her office called me about working with her.''

Ken insists the Spice Girls singer loves to have a lot of ''fun'' in her private time and always tries to avoid taking herself ''too seriously''.

He added to new! magazine: ''She's spontaneous. And she doesn't take herself too seriously. You never know what is coming next!

''She's very good at being herself. She's so much fun, which people don't realise, and she's confident in knowing what she wants. Then she goes out to get it!''
