The 26 year old was all smiles as she stepped out in a 1920s-style veil and white lace Delphine Manivet gown to wave to well-wishers gathered outside the venue.
Despite her fears over a windy weather forecast, the sun was shining as the blushing bride, carrying a small rose bouquet, made her way to the church accompanied by her actor dad, Keith Allen.
Her brother Alfie served as an usher at the event, while Allen's TV presenter pal Miquita Oliver was a bridesmaid.
Guests at the nuptials included U.K. actors Harry Enfield and Angus Deayton, as well as Allen's half-sister Sarah Owen and her film producer mum Alison Owen.
After the ceremony, the newlyweds emerged from the church beaming as they enjoyed their first few moments as husband and wife, before getting into a vintage Bentley car to drive to their reception.
