Prince William Told Off For 'Flirting' At London Charity Event

Prince Harry and the Duke of Cambridge visited London's Docklands today where tried their hands at trading to raise money in memory of those who died in the 9/11 attacks. Here's what happened when they got competitive...

Prince William and Prince Harry never fail to make a room burst into laughter, and today was no different as they played the roles of stockbrokers for a charity event in London.

The brothers visited the BGC Partners HQ in the Docklands where they took part in an annual charity day to raise funds in memory of those who lost their lives in New York's 9/11 attacks. And although their reason for being there was a serious one, that didn't mean that the pair couldn't lighten the mood with a spot of healthy competition – and a few insults, too.

Prince Harry would be our first guess at the brother most likely to get into mischief or be blame for flirting on the job, it was actually Prince William who was accused of slacking… by his own brother.

The Prince joked to the Duke of Cambridge that he needed to 'stop flirting' on the phone and later told onlookers: 'William's on the phone, it's all baby chat. I'm much better at helicopter chat.' Ooh. What will Duchess Kate say?

With their efforts combined, the brothers managed to secure one deal worth over $33 billion.

The BGC Partners building holds the charity day every year to remember the 658 employees they lost to the Twin Towers attacks. Prince Harry and Prince William were also able to raise funds for their charities WellChild and SkillForce. They spent the morning attending the funeral of their father Prince Charles' friend HUgh van Cutsem in Brentwood, Essex, alongside the Duchess of Cornwall.

Tonight, Prince Harry will attend the WellChild Awards in London, while Duchess Kate will join Prince William tomorrow at the Tusk Conservation Awards.

What we wouldn't give to have Wills and Harry visit the MC office… sigh.

Duchess Kate stopped visited which fast food chain?!
