Pictures show the inside of their apartment at Kensington Palace for the first time, which was refurbished with £4.5million of taxpayers’ money - although the couple footed the bill for fixtures and furnishing themselves

Kate had the help of an interior designer, but the look isn’t particularly grand and far from palatial, more comfortable country home

Prince George became the star of the Kensington Palace party after greeting Michelle and Barack Obama in his dressing gown and slippers.

The Obamas arrived at the palace tonight for an informal dinner with Prince William, Kate Middleton and Prince Harry - just hours after the U.S. President's controversial intervention in the Brexit debate.

But it was the two-year-old prince who stole the limelight after pictures emerged of George shaking hands with the leader of the free world wearing his nightwear - a pair of freshly-pressed blue gingham pyjamas, monogramed dressing gown and a pair of slippers with aeroplanes on.

The third in line to the throne was allowed to stay up for a few minutes by his parents, the Duke and Duchess of Cambridge, so the two-year-old could thank the couple for a rocking horse and stuffed toy they had previously given him as gifts.
