The Lady And�The Billionaire...

She has been waiting for this moment since getting engaged in July and now the time has finally come for the Duke of Wellington's daughter to tie the knot with her billionaire fiance.

Lady Charlotte Wellesley, 25, and New York-based financier Alejandro Santo Domingo, 39, are marrying today in Granada, Spain.

Vows will be exchanged at the 16th-century Church of the Incarnation in Illora, before a reception at the Duke of Wellington's nearby country estate. 

And last night the VIPs arrived, including The Duchess of Cornwall Camilla Parker Bowles, the former King of Spain Juan Carlos I, and singer James Blunt, whose wife Sofia Wellesley is Lady Charlotte's cousin.
