Keira Knightley has taken on her biggest role yet: wife.
The actress, 28, tied the knot with her fiancé of one year, James Righton, in an intimate ceremony at the town hall in Mazan, a small village in Provence, on Saturday.
“It was not a long service,” one witness tells PEOPLE, “and very few people.” The ceremony was performed by the village mayor and “occurred just before noon and lasted only about 30 minutes. Keira looked beautiful. She wore a very pretty, very elegant dress.”
Knightley’s choice for her big day? A strapless tulle dress that came to her knees and a classic Chanel jacket. She skipped into the ceremony in nude flats and her hair down, crowned with daisies.
Thirty to 50 guests are reportedly invited to attend an afternoon garden luncheon and an evening party at which Righton’s band, The Klaxons, are expected to perform. Guests are staying at the Chateau de Mazan, a four-star hotel in the village of 6,000. The wedding ceremony and party are being held in Mazan where Knightley has owned a small wine-growing farm since 2010. A reception tent was spotted there on Friday, and the couple smooched in the airport when Righton arrived earlier in the week.
Knightley and the Klaxons keyboard player, 29, got engaged in May 2012, about a year after they were first spotted publicly together. They reportedly met after being introduced by fashion correspondent Alexa Chung.
“We’re not really big-wedding types,” she told Marie Claire in March. “I could have six fake weddings. God, that would be expensive. I don’t need to have all that.”
