Despite Boyd being the inspiration of British folk musician Donovan's song "Jennifer Juniper", they have never been in a relationship, though Donovan admitted having a crush on her. The song was released as a single in March 1968 and on the album The Hurdy Gurdy Man later that year. Also in 1968, Boyd travelled with Donovan and her sister, Pattie Boyd, to Rishikesh, India, to attend a training session in Transcendental Meditation held by Maharishi Mahesh Yogi. Later Jenny shared an apartment with Magic Alex of Apple Corps's Apple Electronics subdivision. She also worked at the Apple Boutique in London.
