Countess Spencer, born Karen Villeneuve, shares a daughter, Charlotte Diana, with the Earl.
Prof Jarman has two sons with her former husband Tom Jarman.
The Earl proposed to his first wife, Victoria Lockwood, just six weeks after meeting her.
The couple married in September 1989 and had daughter Kitty, twins Amelia and Eliza, and Louis, Viscount Althorp.
When the children were young, Ms Lockwood relocated with them to Cape Town to escape media attention generated by the Earl’s sister, Princess Diana. They filed for divorce in 1997.
The Earl went on to marry Caroline Freud, the former wife of Matthew Freud, a PR executive, in 2001.
The pair had been friends since their student days at Oxford.
They had two children, Edmund and Lara, and divorced after five years of marriage.
