Is Prince Harry under a lot of pressure from Prince Charles to break up with his girlfriend Cressida Bonas? According to a new report, Prince Charles is not convinced that Prince Harry's girlfriend Cressida Bonas is "royal material."

Prince Harry, 29, was rumored to want to settle down and get engaged soon to his girlfriend Cressida Bonas, 24, but now ShowbizSpy.com reports that the young royal has been told to break up with his blonde beauty.

"Harry had a meltdown after his father told him to 'back off' from Cress because of her family problems," a source said, the website reports.

"Charles has been thrilled that the Royal family's credibility was restored after Prince William married Kate Middleton and (their son) Prince George was born.

"Charles doesn't want Cress' family problems to cost them all that good will."

Cressida's stepfather - former investment banker Christopher Shaw - was found dead of a suspected drug overdose at his home. Shaw, 76, was the fourth husband of Cressida's mother, the website reports.

"Harry told his dad he loves Cressida, but Charles isn't sure she's royal material," the source continued.

"Harry is under huge pressure to dump her, and friends say he's 'broken in two' at being torn between his family and his lover."

Yet on the other hand, Harry and Cressy were spotted only weeks ago driving back to Kensington Palace after a casual burger date - if their relationship was causing tension, it seems unlikely that they would want to spend time around the royal family.

"They were having a good time," a source at the burger restaurant told People magazine.

Harry and Cressy have been dating for almost two years. According to the Daily Beast: "Harry has told friends that Cressida is without a doubt the most serious relationship he has been in, eclipsing even the Chelsy years, and that he remains committed to her," the publication writes.
