Prince Harry had a tough conversation with Prince William about Meghan Markle and Kate Middleton's relationship, a new book claims.
In his new book 'Revenge: Meghan, Harry and the War between the Windsors', the author acknowledges that the pair's relationship hasn't always run smoothly.
Both married to members of the Royal Family, the duo have a lot in common but never seemed to click.
Previously, in a bombshell interview with Oprah, the Duchess of Sussex accused her sister-in-law of making her cry over bridesmaids' dresses.
Countless reports over the years suggest there have been tensions - with one insider simply saying they are "very different".

Now in his new book, Tom Bower claims that while Harry and Meghan were preparing for their official visit to Australia and New Zealand, Harry suggested to William that Kate should be 'friendlier 'to his wife.
The book says: "Members of their family, said Harry, were not showing her sufficient support, respect and friendship. Meghan, Harry believed, should be just as appreciated as their mother
"William’s reply was not sympathetic. Beyond the palaces, few were aware of the split between the brothers."
Meghan and Prince Harry made a number of claims about their time as working members of the Royal Family in the Oprah interview - with reports alleging Meghan made Kate cry during a bridesmaid dress fitting.
But during her one-on-one with Oprah, Meghan claimed it was actually Kate that made her cry.
Now in Tom Bower's sensational new book, he has included new details about the bust-up between the two - and how it soured their bond.
He alleges that the pair fell out over whether Princess Charlotte should wear tights, and if the dress fitted properly.
In Andrew Morton's book Meghan: A Hollywood Princess, the author previously claimed that Kate didn't have "much energy" to bond with Meghan in the lead-up to the wedding as she was going through a difficult pregnancy with Louis.
Meghan said she has now forgiven Kate, adding that she's a "good person" and that Kate sent her flowers to apologise for the incident -although gave no details on what sparked the incident, and it is still not known for certain.
