The Duke of York is reported to be dating a former model to whom he was introduced by his ex-wife.

Millionaire's daughter Heather Mann, 28, began seeing Prince Andrew after they met earlier this year.

Ms Mann, who now works as a gems specialist at Christie's in London and once dated Prince Albert of Monaco, has stayed with the prince, 38, at his home in Berkshire and at Buckingham Palace and Balmoral.

The pair are said to have met five months ago after they were introduced at a party by the Duchess of York.

Of her visit to Balmoral, Ms Mann, who admits she knows the prince, said: ''The invitation was issued by a friend of Prince Andrew's who was there.

''It was not by Prince Andrew.

''The acquaintance called me and said, 'I'm here - you are more than welcome to join us for the afternoon,' which I did.

''That's all there is to it. It was very enjoyable.''
