The 31-year-old "Keeping Up With The Kardashians" star fell in love with the city on her recent trip here and the couple hope to explore their mutual love of British culture by buying a home in the English capital, reported Us magazine.
"They are fascinated with British culture. They both feel so welcome there and are ready for a change of scenery and new challenge. Kim likes the idea of a cute two or three bedroom town house near one of London's beautiful parks," a source said.
The news comes a month after the couple was seen house hunting in Miami.
They looked at four waterfront homes in Florida, with all the properties priced between USD 7 and USD 10 million.
