I think some years ago Fergie moved back into the house, despite their being divorced. The Wikipedia article gives a lot of detail about their living in the same houses or vicinity over the years since the divorce. Even this most recent move out of the Royal Lodge had her moving out, now "making her own living arrangements." But I'd bet they'll still be nearby.

And she has a role in the Epstein files discussion:

In March 2011, it was reported that Jeffrey Epstein, a convicted sex offender, had helped Ferguson avoid bankruptcy by paying £15,000 to an employee to whom she owed money.[88] The payments were reportedly made after intervention from Andrew, who had a close friendship with Epstein for which he came under scrutiny in 2019.[89] She later admitted getting money from Epstein and called it a "gigantic error".[90] In the summer of 2011, Finding Sarah aired on the OWN network. One episode of the U.S.-filmed reality series depicted Ferguson meeting with Suze Orman, the internationally known financial advisor, receiving from Orman a strict lecture and practical advice on how to resolve her financial issues.[91] Juan Alessi, a staff member at Epstein's Florida residence for 12 years, said in an unsealed deposition that he believed Ferguson visited "only once and for a short time".[92][93][94]
