Kate Middleton doesn't like the idea of Prince Harry and ex-girlfriend Cressida Bonas getting back together, and is allegedly urging the prince to reconsider his decision in reconciling with Bonas, OK! reported.

It was previously reported that the Duchess of Cambridge thinks that Chelsy Davy will be a perfect wife for Prince Harry and not Bonas. Middleton "vetted both Cressida Bonas and Chelsy Davy" and she "questioned whether either woman was up to the rigors of royal life. And, although Chelsy has confessed some fears about royal life – Kate managed to calm them all," Star Pulse noted.

The internet has been running wild buzzing about Prince Harry and Bonas getting back together. The two broke up in 2014 after a two-year relationship. They were first spotted together in February 2013 while skiing in Verbier, Switzerland. After their break up, the two remained close friends, wherein Bonas was even invited to attend Harry's 31st birthday, as well as was seen leaving the party early morning the next day. The said incident sparked controversy about the two's reconciliation.

"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," a source said.

Middleton's issue with Bonas is due to the fact that Prince William once dated Bonas' half-sister Isabella Anstruther-Gough-Calthorpe. She also think that Bonas might hurt Prince Harry again like what happened before.

"Kate is afraid that William sees Isabella as the one who got away. She hates even hearing Isabella's name mentioned," the source added, according to International Business Times. "She was obviously upset when Cressida and Harry started dating. Kate has even told William to warn Harry against her. She does not trust Cressida," continued the report.

Aside from Bonas, Harry also sees another ex-girlfriend, Davys, whom he spent time with in Africa during his three-month tour. With that, the Duchess is hoping that instead of Bonas, it will be Davy's and Prince Harry's relationship that will be rekindled.
