Sarah Ferguson has gone into detail about her unusual living arrangement with former husband Prince Andrew.
And Sarah, who is also known as Fergie by royal watchers, has explained that the former couple have a co-parenting relationship,
The 61-year-old got married to Andrew in 1986, but ended up splitting with the naval officer in 1991.
The couple were said to hardly see one another after it was revealed Andrew's job meant they were only together for 40 days a year during the first five years of married life.
Fergie, who has penned new novel Her Heart for a Compass, has now revealed to the Sunday Times how she and Andrew live following their split.
She said: "We are very good co-parents together."
She also talked about her decision to stay at Andrew's home, Royal Lodge in Windsor, during her UK visits.
She said: "I travel a lot and I’ve always been able to make wherever I am home.
"If I am staying in a hotel I have the same family photographs and scented candles around me.
"When I’m in the UK I’m lucky enough to stay at Royal Lodge. I wouldn’t call it my home as that would be presumptuous."
Andrew's former wife recently called him a "great man" on Good Morning America.
She said: "He is a great man and [our wedding day] was the best day of my life.
"I would do it all over again because he was a very good-looking sailor, but I fell in love with him and I think love conquers all."
Sarah also spoke about her mental health battle in The Sunday Times, saying she sometimes finds it hard to manage because she is so sensitive.
She said she has a therapist and relies on friends, family and work to "keep her focused on what's important".
She added that she is "never complacent" about having been "the luckiest girl ever".
