Victoria Beckham is paying for her sister's £50,000 wedding.
The former Spice Girls singer has offered to organise and fund every aspect of her younger sibling Louise's marriage to stockbroker Darren Flood on December 27.
A source said: "Victoria just told Louise, 'I don't care what it costs - it will be my Christmas present to you.’ Louise was very emotional."
Victoria wants the event to be held at her 'Beckingham Palace' mansion in Hertfordshire, East England, and has even asked fashion designer Vera Wang – who created the gown Victoria wore for her 1999 marriage to David Beckham – to make Louise's dress.
But the star’s generous offer has upset Darren, who wants to pay for the nuptials himself.
The source said: "He is insisting he gets the bill - it's why he is so respected and liked by the family. But Victoria normally gets her way."
It won't be the first time Louise has walked down the aisle at 'Beckingham Palace'.
Her first wedding was held there in 2002, but the couple split five years later in 2007.
