Keira Knightley has walked down the aisle - but only as bridesmaid at her brother's wedding and Breaking Celebrity News has the photos.

Wearing a beautiful burgundy dress and with a bouquet in hand, the British actress was all smiles as she watched her older sibling, Caleb marry his sweetheart, designer Kerry Nixon.

In a very nontraditional move Keira and the bride arrived at the Pollokshields Burgh Hall in Glasgow, Scotland in a white taxicab.
