All signs pointed to a future royal wedding between Prince Harry, 29, and his longtime girlfriend, Cressida Bonas, 25. But according to new reports, the couple is rumored to have called their romance quits.

“Harry and Cressie have split,” a source told ShowBizSpy.com on Monday, citing the pressures associated with marrying into Britain’s royal family as the main reason for the couple’s break up after two years together.

"Cressie is still young and have huge reservations about marrying into the royal family. They had a chat over the weekend and decided it’s best they cool things off,” an insider said. “Harry’s hoping she’ll change her mind but for now, the romance is very much off.”

So who's to blame for the split? According to a published report in Star magazine (via CelebDirtyLaundry.com), Kate Middleton, Prince Harry’s sister-in-law and wife to the Duke of Cambridge, Prince William, might have been the catalyst that caused their relationship to end.

“Cressida wants to slow things down,” a source told the tabloid, adding, “Cressida has spoken with Kate about the expectations that come with being part of the royal family and how unbelievably busy she is … Kate’s been honest about her struggles and it’s been a lot for Cressida to process.”

While a majority of publications are reporting that Bonas, a former model, has called off her rumored upcoming engagement to Prince Harry over cold feet, other publications are claiming that she's too busy to jump into a marriage.

“She has just started a new job where she’s being paid the usual salary of someone her age -- i.e. peanuts -- and she has found a flat to rent with her friend Daisy. She is doing all the things that people in their 20s should be doing,” a source told the Daily Mail last month. “Who knows what might have changed by this time next year, but that is how she wants it to be.”

Bonas and Prince Harry first sparked rumors last February after the duo was spotted skiing together in Verbier, Switzerland. The couple was reportedly first introduced by Bonas’ friend and Prince Harry’s cousin, Princess Eugenie of York, in May 2012.
