The beautiful blonde and her musician love, 30, tied the knot in front of close friends and family at the Lime Wood Hotel, near Lyndhurst.
Having hired out all of the 29 bedrooms at the picturesque country house location for their guests, the couple - who met at charity event two-and-a-half years ago - were united in a civil ceremony.
Model Sophie, 32 – the maternal granddaughter of author Roald Dahl and actress Patricia Neal – was given away by her actor father Julian Holloway and wore a beautiful ivory Versace-style dress for the occasion, the Mail reports.
Her mother Tessa, half-brothers Ned and Luke and her half-sister Clover were there proudly looking on.
"It was a very beautiful occasion for close family and friends," the bride's godmother said of the happy event. "Sophie looked absolutely fantastic."
The couple's plans to wed were first made public back in April when the former catwalk queen-turned-author was spotted with an engagement ring on her finger at a London party.
Ahead of his nuptials, Jamie – who along with Sophie has frequently laughed off comments about their difference in height - recently recalled the first time he met his new wife.
"We hit it off immediately. I think we knew emotionally that we would become good friends," he said.
"But someone like me never entertains the idea of going after someone like her, so I didn’t go for it. I couldn’t assume she would be interested in me…But it worked! Lucky old me – it turned out to be much more."
