It looks like there may be trouble in paradise for Prince Harry and his girlfriend Cressida Bonas seeing as some of the royal of Wales' close circle of friends and family thinks that the blonde beauty is not the right woman for him.

According to E! News, some people close to Prince William's little brother are saying that the 29-year-old red head should get married to the 25-year-old dance student.

A source said, "There is a growing feeling among a small section of them that Cressida isn't the perfect choice for him," adding, "I don't think it's because there is anything wrong with the relationship or they don't like her, but there is concern that she is too much of a free spirit to be happy in the royal family long-term.

"They worry that she wouldn't be able to fully adapt to that lifestyle. They think she's too carefree and would find it difficult to live by the protocol that comes with the job, which of course it is. It might be too much of a constraint for her. And that could cause problems for everyone."

News of doubts on the romance comes on the heels of a report claiming that Harry and Bonas have been talking about marriage.

Last month an insider revealed, "Harry and Cressida have made a point of talking about marriage and what changes they're going to have to make to their life of late."

The source continued, "According to friends of Cressida's, the couple have decided to try and keep their semi normal lifestyle as long as physically possible."

Another source of the attractive pair explained that the two were becoming stronger than ever. The insider admitted, "Harry and Cress are just a great fit-she just fits into his life, with his friends. It's all been really easy."

The insider added, "They spend loads of time together, she has a load of stuff at his place and they're really relaxed and comfortable."

However, Cressida Bonas has become fully aware of just how drastically her life would change if she married Prince Harry of Wales.

A royal insider revealed, "Up until now, Cressida has loved the fact they can have a lot of freedom in public," adding, "But they are fully aware once they decide to proceed to marriage things will get a little crazy and the attention on them will increase."
