Speaking about her big day for the first time, she told The Mirror happily: “I secretly organised it,” she says, talking about her big day for the first time.
“We got to Vegas and I’d invited our friends Trent and Emma to join us from Canada. That was the first surprise.
“The next day at lunch I leant over to Matthew and went: ‘Darling, I have something to run by you… I have planned for us to go to the Little White Wedding Chapel and renew our vows.’
“He was like: ‘Oh my God! That is so embarrassing!’”
Thankfully, however, she was able to cheer her husband of 15 years up with an extra newsflash; he didn’t have to get all dressed up for the impromptu ceremony.
“Matthew’s next words were: ‘I don’t need to wear anything do I?’
“He thought I was going to slide off and put on my wedding dress.
"But we went as we were. I had white shorts and a white top on – I thought that was quite bridal.”
She added naughtily: “I didn’t have an Elvis, though. I thought that might push Matthew over the edge.”
Davina and Matthew’s children wrote the vows - and the whole ceremony wound up being “funny and moving”, according to the TV presenter’s Instagram post.
