Prince Harry and his girlfriend Cressida Bonas engagement and wedding rumors of them tying the knot are simmering down - is Prince Harry thinking Cressida Bonas is too normal to be his future royal bride?

Prince Harry's girlfriend Cressida Bonas was spotted heading down the stairs to the Tube, the London subway, carrying a green smoothie with her headphones in her ears. She was wearing skinny jeans, an oversized T-shirt, and dark coat. Her face looked makeup-free. Is Cressida Bonas too normal to be Prince Harry's fiancee one day? We have to admit, she's worlds away from his brother Prince William's wife, Kate Middleton, who is rarely seen without a flawless face and enviable blow out.

As we previously reported, Cressida Bonas hasn't been seen in public with Prince Harry for some time. She skipped out on Harry's late-night hang out with some rugby friends and also did not attend the wedding of Lucy Meade and Charlie Budgett as Prince Harry's date - he went solo, but was accompanied by Prince William and Kate Middleton.

Is Cressida Bonas hiding from the media to deter engagement and wedding rumors? If she is, it's working: the buzz around their relationship has died down in recent weeks.

"People talk to her all the time about Harry and she gets quite cross and says 'I don't want to get married yet,'" a friend of Cressida Bonas' told the Daily Telegraph.

"She hasn't been invited to meet the Queen yet, so she's not at the stage of an engagement being imminent."

Prince Harry will be 30 this September, a typical age for members of the Royal family to marry, The Daily Telegraph reports.

"If it was up to Harry he would get married straight away but he is very sensitive about her on this particular issue," said a source. "Harry has told her he will wait."

Harry and Cressy have been dating for about two years.
