Celebrity chef Jamie Oliver and his wife Jools have been voted the most naturally fitting couple in the UK.
The Olivers beat the daytime TV couple Richard and Judy Finnegan and Prince Charles and his wife Camilla, who came in third place.
Jamie and Jules were married in 2000 and have two children - Poppy Honey and Daisy Boo. The couple took 17 per cent of the vote in the poll by Huggies Natural Fit Nappies, edging out Richard and Judy by just one per cent.
Dr Pam Spurr, a relationship expert, said: "Jamie's down-to-earth personality, paired with Jules being perceived as a supportive partner, gives them fantastic appeal.
"And whether you're a fan of the royals or not, third-placed Charles and Camilla seem to fit together like a pair of comfy old slippers.
Dr Spurr added that despite the "well-documented ups and downs of their relationship", Charles and Camilla's happy marriage has struck a chord with people "at an emotional level".
Former England captain David Beckham and his wife Victoria came fourth in the poll, living their life in the full glare of the media, along with Beckham's former team mate Wayne Rooney and Colleen McLoughlin who were in seventh place.
A few couples who made the worst fitting list included Courtney Love and Steve Couganl; the recently separated Britney Spears and Kevin Federline; and chancellor Gordon Brown and prime minister Tony Blair.
Big Brother contestants Nicky and Pete were also regarded as not having a naturally fitting relationship after they separated after just a few weeks together.
