It seems like Duchess Catherine has a stronghold on Prince Harry, when it comes to his love life at least. There's a new report that says the Duchess is none too happy over the fact that her brother-in-law is still interested in rekindling his romance with Cressida Bonas. She has been hoping that Prince Harry would seal the deal with his ex-girlfriend Chelsy Davy, only because she has a personal interest in his affairs.

According to OK! Magazine on Wednesday, the Duchess apparently has an agenda against Bonas and wants her to stay as far away as possible from the royal family.

A source close to the British royal family dished, "Kate doesn't like Cressida at all. It's not just that she thinks Cressida isn't a love match for Harry. It goes deeper than that. She doesn't want her in the family."

Apparently, Kate Middleton's husband, Prince William once had an affair with Bonas' half sister Isabella Anstruther-Gough-Caithorpe. If Prince Harry did indeed decide to marry Bonas, that would mean her entire family, including her half-sister, would be spending more time at Kensington Palace than the Duchess would like.

The insider said that Kate is "afraid that William sees Isabella as the one who got away."

"Kate hates even hearing Isabella's name mentioned," the source said. "She was obviously upset when Cressida and Harry started dating."

Prince Harry, meanwhile, doesn't seem to be worrying, as he's been insisting that he's currently single and in no rush to get married.
