Cressida Bonas currently holds the coveted title of being a royal girlfriend, but she won't upgrade to become a "trophy wife" like Kate Middleton. At 24, Prince Harry's girlfriend allegedly thinks she is too young to settle down, and gets scared of her royal boyfriend's talk of marriage.

The young socialite has reportedly been telling friends that she doesn't want to be a trophy wife to the 28-year-old British prince, adding that she is far too young for matrimony. This is unfortunate for Harry who already wants to get married.

"Sadly for Harry, she thinks she is too young to do that," a friend told The Sunday People. "She likes to go out and enjoy herself and is a long, long way off being anyone's wife let alone a royal wife."

Cressida wants an acting career, and that would be impossible for her to get that if she marries the third in line to the throne.

Her reluctance is said to be creating trouble with their relationship, which already has "irreconcilable" problems to begin with. While she possesses the right credentials to become Harry's wife, it's not enough for him to remain interested. He is apparently getting tired of not getting what he had hoped from their relationship.

Also, it's still ex-girlfriend Chelsy Davy who is still in his heart. Reports claim that he still can't get over the 27-year-old Zimbabwean national, whom he dated on-and-off for four years. But like Cressida, Chelsy wasn't into the royal life.

It's also rumoured that Kate Middleton, Harry's sister-in-law, isn't too fond of Cressida for Harry. Her husband, Prince William, and Cressida's half-sister, Lady Isabella Calthorpe, reportedly tried to date once upon a time.

The feeling is mutual, though, since Cressida isn't fond of Kate as well. Last month, Now magazine quoted sources who claim that Cressida and her half-sisters Isabella and Gabriella think that Kate and sister Pippa are from "the other side of the tracks," referring to their commoner background.
