Victoria Beckham has opened up about being bullied ''mentally and physically'' at school and said she wants to use her experiences to educate her daughter on the importance of being kind.

The 44-year-old fashion designer, who has children Brooklyn, 20, Romeo, 17, Cruz, 14, and Harper, eight, with husband David Beckham, insists she wants to teach her daughter the importance of girls being ''kind'' to other girls.

Speaking to Glamour magazine,  Beckham said:  ''I was bullied a lot at school, mentally and physically and the fact that I can talk to Harper about that and how girls should be kind to girls... I use my own experiences.''

Beckham believes it is important to set a good example to her kids so that they know how to be ''healthy and happy'' with themselves.

''When you have children, it also puts a lot into perspective. You realise they notice everything.

''I would never sit down with my kids and skip a meal - they need to see that their mum eats healthily - you need to show little people how to be healthy and happy with who they are," she added.

The former Spice Girls singer has previously spoken of the ''hell'' she went through during her time at secondary school.

"Secondary school was hell. Children picking things up out of the puddles and throwing them at me. I just stood there, on my own. I didn't have any friends.

''People would push me around, say they were going to beat me up.''

Beckham reckons she was singled out because of her appearance from a young age but claimed the bullying gave her a ''very thick skin''.

''I was a skinny, sallow-faced eight year old with pigtails and a gap in my teeth big enough for a pea to get stuck in. It was miserable. I didn't fit in.''
