Pippa Middleton, the Duchess of Cambridge's sister, will be a spring bride as she walks down the aisle at her family church in May next year.
According to friends, the ceremony will take place on Saturday May 20 at St Marks' Church in Englefield, Berkshire, with the reception taking place back at the Middleton family home in Bucklebury a few miles away.
Prince George, three, Pippa's nephew, is tipped to be a page boy and her niece Princess Charlotte, who will have just turned two, a flower girl.
The Duchess of Cambridge's little sister shot to public attention when she wore a bottom-hugging bridesmaid's dress at the royal wedding in 2011.
But she is said to have wanted a smaller, more intimate 'family' wedding when she weds wealthy hedge fund trader James Matthews next year.
The couple are believed to be setting a marquee up in the garden of Michael and Carole Middleton's mansion with posh Portaloos brought in for the occasion.
Trendy designer Giles Deacon is rumoured to be making Pippa's dress after he was spotted carrying garment bags into the £17 million house with his and hers bathrooms she and James share in London.
Chelsea florist Lavender Green is arranging the flowers - likely to include spring blooms like daffodils.
