News of Prince Harry and Cressida Bonas' break-up has only been public for a matter of days, but already Kate Middleton, the Duchess of Cambridge, has been blamed for causing problems in their relationship.
"Kate and Cressie just didn't get along," a source told Showbiz Spy.
"William had words with Harry, and told him friction between between the women could cause a major problem in the long term."
However, there's still hope Harry and Cressida might reunite. Their break-up has been described as a "breather" and one source said the two are still very close.
"It's very sad that they have decided to split but this is a completely amicable separation and they are remaining the very best of friends."
So - perhaps more royal nuptials will be on the cards for the couple eventually? (William and Kate also had a brief "on a break" period before their marriage.) Although, it doesn't sound like the duchess will be involved in any of the wedding planning...
