James Righton and Keira Knightley

Keira Knightley held a secret second wedding last year.

The 29-year-old actress, who married The Klaxons rocker James Righton in front of just 11 family members in Mazan in the south of France in May 2013, has revealed they enjoyed another private celebration for their friends afterwards.

The 'Begin Again' star, who wore her favourite white Chanel mini-dress for her first nuptials, donned a bespoke wedding gown by Valentino, covered in pink flowers, for her second walk down the aisle.

The brunette beauty told the July edition of the UK's Elle magazine: "I wore it for the ceremony we had just for our friends, in a wood, because you have to have flowers on a dress in a wood."

Following their original wedding, Keira and James returned to her family's $5 million vineyard in Provence in a silver Renault Clio and held a reception for 50 guests.

He previously said: "We had a beautiful wedding and there was a lot of love."

The British keyboardist, 30, gave Keira his grandmother's wedding ring.

A source said at the time: "The ring he gave her was a family heirloom. He really did think it all through. It was an amazing wedding, the whole thing was really sweet and down to earth."

The couple got engaged in May 2012 after meeting through mutual pal Alexa Chung.
