Keira Knightley tied the knot with her musician boyfriend James Righton in a low-key ceremony in the south of France this morning (May 4).

The Anna Karenina actress exchaged vows with The Klaxons star in front of a small congregation of 11 of their close friends and family, reports The Daily Mail.

The couple married in the town hall in Mazan, a small town near Marseilles.

The 28-year-old star went for a laidback wedding look, wearing a white knee-length ballet-style dress which featured a tuille skirt.

She chose a pair of pale pink pumps and a chic Chanel boucle jacket, along with black sunglasses and a simple flower headband, to finish off the look.

Knightley chose a silver Renault Clio to pick her up from the wedding and bring her to the reception, which was about three miles away.

An onlooker said: "It was a very moving ceremony. Keira looked extremely moved by the whole thing - there were certainly tears of happiness.

"It was sunny day without a cloud in the sky. There were cheers of 'Well done, Keira' when she came out, but there were so few people present so they didn't make much noise.

"It was amusing to see them being driven away in a battered old Renault Clio - it certainly looked as though it had seen better days."
