In 1963, while she was married to Robert Freeman (who had recently begun his professional relationship with the Beatles), John Lennon was looking for a home to rent in London for himself and his wife Cynthia. Freeman suggested that the couple take a flat in the same building in the South Kensington area of London that he lived in. Freeman had become a good friend of the Beatles and socialized with them. Writer Philip Norman says that Sonny also joined Freeman in socializing with Lennon and his wife. He further says that she became personally close to Lennon, and that they would often stay up late together talking "about things like life death, the way you do when you're young."
