The pop singer and his wife Kristina appeared on a celebrity edition of the BBC show Escape to the Country, where they enlisted the help of presenter Jules Hudson to find their dream home in the countryside.
With a budget of £1.3 million, the couple hoped to find a character property with modern features, four double bedrooms, space for a music studio, and a garden for their dogs.
Host Jules Hudson said: “Not the easiest to find.”
The property search began in the Gloucestershire village of Edge, followed by a visit to a converted pub in Ashton Keynes, North Wiltshire.
The episode took a musical turn when Mr Hawkes paused the house hunt to teach Mr Hudson a few guitar chords, leading to an impromptu song around an outdoor fire.
The presenter also hosted a light-hearted quiz in one of the homes, challenging Mr and Mrs Hawkes to identify famous musicians and recall major events from 1991, the year The One and Only became a hit.
Later, the couple viewed a five-bedroom property in Chalford Hill before touring the show’s largest-ever mystery house, a 17th-century manor in Sevenhampton.
In the end, Mr and Mrs Hawkes said they particularly liked the third property but had not yet made a decision.
Kristina Hawkes said: “What you definitely have shown us is that the Cotswolds is very, very lovely.”
The search is ongoing.
