Keira Knightley has walked down the aisle - but only as bridesmaid at her brother's wedding and RadarOnline.com 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.
Keira's date for the big day was her new boyfriend, Klaxons rocker James Righton, who she has been dating for two months following her split from longtime love, Rupert Friend.
The 26-year-old star is currently starring in a West End production of The Children's Hour.
