Marriage history

During their marriage, they collaborated professionally, composing and performing the theme tune for the children’s series Button Moon (TV Guide) and appearing together in the 1983 holiday pantomime Cinderella (Wikipedia).

Divorce and remarriage

After their divorce, both pursued separate lives. According to IMDb, Dickinson married Mark Osmond on August 16, 2009. However, multiple biographical sources, including the Wikipedia entry, report that she and Davison remarried in 2019. As of 2025, no definitive public record has resolved the conflict.

Current relationship status

Public references to Dickinson and Davison as a married couple exist, but the lack of a verified primary source means the question is unresolved. The Storyshift profile also notes the 2019 remarriage, but its tier-3 sourcing offers less authority than direct records.
