The newlyweds, who have been dating for three years and have a 15-month-old son named Rex together, both looked picture-perfect on their special day.
Fearne wore a short-sleeved white dress with glittering sequin detail on the neckline, a beaded Alice band and strappy white heels, while guitarist Jesse, 37, sported a grey suit and a bright blue tie, accessorising his outfit with sunglasses.
London-born Fearne recently spoke about how eager she was to tie the knot with Jesse.
"I can't wait to be a wife," she said. "It just feels really solid. I want to have the same surname. I want to feel like we've done it properly."
True to her word, the day after her nuptials Fearne tweeted "Good morning everyone from a very happy Mr and Mrs Wood".
