Prince William will have to try and keep up with his little brother

Prince Harry is sure to give his brother a good send off before he marries Kate Middleton in April.

Fresh video footage of a young Harry on an African holiday with ex girlfriend Chelsy Davy a few years ago shows him playing wild drinking games with his mates – and snorting spirits up his nose.

Harry works his butt off to be the best soldier he possibly can,’ says a source.

‘And like all soldiers he really enjoys letting off steam from time to time.

‘As usual Harry led the drinking and was the first to have a go at standing up while being spun round dizzy.

‘The booze snorting was just one of the occasional things young people do when they are partying.

‘It’s not at all something the prince makes a habit of.’

We imagine Harry, now 26 – also known as Prince Of Fun – may have a job on his hands if he wants to persuade his 28-year-old big brother to really get reckless before his wedding on 29 April.

William is much more reserved, even a little shy,’ a royal observer tells The People.

‘So he’d better beware what Harry is lining up for his stag holiday.

‘With Harry‘s sense of mischief it will be no holds barred.’
