London, July 9 (IANS) Former Spice Girl Victoria Beckham makes sure her three sons know when they have done wrong by sending them to a special ‘punishment chair’ they have in their home.

The 36-year-old singer-turned-fashion designer who has three children – Brooklyn, 11, Romeo, seven, and Cruz, five – with English football star David Beckham, is very strict with her kids but has never ‘physically’ punished them for bad behaviour, reports femalefirst.co.uk.

‘We have got a punishment chair in our house. When you’ve done something naughty you are supposed to sit down on it and think over your behaviour. But I have never had to punish them physically,’ said Victoria.

‘I think they are all very clever boys, and besides that they have got very good manners,’ she added.

Victoria also said the couple is very strict about their kids doing homework and the time for going to bed.
