The statuesque model and the jazz musician had a blessing and reception at the Lime Wood Hotel in the New Forest National Park near Lyndhurst, Hants. They had sealed their union earlier in a civil ceremony.
The nuptials had a winter wonderland theme and the venue was lit with hundreds of fairy lights. The blessing was followed by a wedding breakfast in a marquee with food preferred by a Michelin-starred chef.
Only close friends and family knew of the wedding, after the couple turned down big-money magazine offers and opted to keep things private. Cullum said recently that they wanted the wedding to be “really private and small – as small as it gets”.
Cullum, 30, performed at the reception. Dahl, 32, wore an ivory “Versace-style” dress and was given away by her father, the actor Julian Holloway.
A spokesman for the hotel said: “They looked very happy. They had a celebration of marriage and a wedding reception.” A spokesman for the couple confirmed the wedding and said they were now on honeymoon.
The couple met in 2007 and announced their engagement in March last year.
The height difference between the pair – Dahl is several inches taller – has been the subject of much joking in the press, but Cullum said last year: “It’s very hard to see it as a problem when we’re very happy. And obviously we’re happy. It’s a positive thing – we’re getting married, we’re going to spend the rest of our lives together. It’s very hard to take the shine off that.”
Dahl, granddaughter of the late children’s author Roald Dahl, has swapped modelling for cookery, bringing out a recipe book and fronting a BBC Two series, Miss Dahl’s Voluptuous Delights.
