Countdown's Rachel ties the knot

Aisle have a vow please ... Countdown star Rachel Riley has tied the knot with her university sweetheart watched by her Channel 4 pals.

The maths whiz swapped consonants for commitments as she married Jamie Gilbert with guests who included programme host Nick Hewer.

Rachel, 26, who replaced Carol Vorderman on the daytime show, told Hello! magazine: "It was only when we were walking down the stairs to the ceremony that I got a bit nervous.

"We were getting in position, ready to make our entrance when my dad stood on my dress. So he kind of fell over."

Rachel added: "As soon as I saw Jamie, I was waiting for his reaction to my dress."

"She looked amazing," said her new husband.

Hewer, who posed alongside the happy couple for the magazine, puckering up for a kiss on her cheek, said: "Of course, Rachel is one of the most beautiful women in England. When you've got brains and beauty combined, then you've hit the jackpot - at least Mr Gilbert has."

Her proud dad Chris said his brainy daughter, who studied at Oxford, is a "maths geek and proud of it".

He added: "I've watched every Countdown numbers game since Rachel started on the show, that's 2,448," he said.

"Rachel has solved the numbers game when contestants have failed and she's done this over 700 times."
