'So how many wives does your husband have m'dear?' Flirty Prince Philip charmed by the Emir's 'Sheikha'

It's all smiles as the Queen officially welcomes the Emir of Qatar to Britain today with a ceremony full of pomp and pageantry amid the regal splendour of Windsor Castle.
And Prince Philip proved that even though he's 89 he can still spot a beautiful lady, as he shared a private joke with the Emir's third wife, stunning 50 year old Sheikha Mozah bint Nasser Al-Missned.
Sheikh Hamad bin Khalifa al-Thani and his wife are the monarch's guests at Windsor Castle during a three-day state visit.

After the official greeting in the grounds of Windsor Castle where the Emir, accompanied by the Duke of Edinburgh, reviewed a Guard of Honour, the royal group had lunch.
The Emir will visit Downing Street for talks with David Cameron and Westminster where the Gulf ruler will address the All Party Parliamentary British-Qatar Group, peers and MPs.

In the evening the Queen will host a state banquet for the foreign royals at Windsor Castle where both the monarch and her counterpart will make speeches.
The oil- and gas-rich Gulf emirate has a growing influence in Britain and has seen some high profile developments in recent years including the acquisition of the world famous Harrods store for a reported £1.5billion in May.

The Forbes list of richest monarchs puts Sheikh Hamad bin Khalifa Al Thani in eighth place with a fortune of $2.4billion, ahead of our own Elizabeth II who is ranked twelfth richest.
Not including the value of Buckingham Palace or the British crown jewels, which belong to the nation, the Queen owns valuable property in England and Scotland, fine art, gems and a stamp collection, all of which is estimated to be worth a combined $450 million.

Qatar invested more than £2billion in Britain last year, and ministers hope the country's vast wealth could help an export-led recovery.
The coalition Government is attempting to 're-energise' Britain's standing with the Gulf states focusing on culture, business and defence relations. Last week British ministers met their Middle East counterparts at the Foreign Office to discuss the issue.
Qatar, a British protectorate until 1971, is the gateway to Afghanistan for the UK's military, while a large amount of the country's profits from its gas reserves are invested through London's Square Mile.
Qatar also has a 6.8 percent stake in British banking giant Barclays and a 25.9 percent share in the Sainsbury's supermarket chain.
Meanwhile the Emir himself is said to own sumptuous super-yachts, and property owned in London includes his £37.4m mansion in London’s Park Lane.
On Wednesday, the Emir will visit the stadium for the 2012 London Olympics and, with Qatar bidding to host the 2022 football World Cup, he will hold discussions with officials on England's bid to host the 2018 World Cup.
