It cannot be denied that Kate Middleton, 37, and Prince William, 36, have become favorite subjects of malicious rumors and speculations due to their influence and popularity. The Duke and Duchess of Cambridge have been bombarded with various allegations, from pregnancy, cheating, to pregnancy speculations. Now, recent reports claimed that the mother of Prince George, 5, Princess Charlotte, 4, and Prince Louis, 1, also have an attitude problem.

Rumors claimed that sightseers noticed Kate being "moody" during the horse-drawn ride at Trooping the Color event earlier this month. Most fans can recall that the wife of Prince William shared a carriage with Duchess of Cornwall Camilla Parker-Bowles, Meghan Markle, and Prince Harry. While the other members of the Royal family were all smiles during the ride, many felt that Pippa Middleton's sister did not enjoy the ride.

This, according to speculations, could be because of the rumored rift between Kate Middleton and, Meghan and Prince Harry. Previous reports claimed that Kate and the Sussexes are not on good terms after Meghan and Prince Harry moved out from the Kensington Palace. Kate and Prince William were, allegedly, jealous of the attention that Meghan and Harry have been getting since their wedding.

It is being claimed that Kate and Prince William felt that Meghan Markle and Prince Harry stole the spotlight from them. Other speculations even suggested that things had exacerbated when Archie was born since several media outlets have given so much coverage to the Royal baby.

However, a Royal source hinted that Kate Middleton's moodiness, at the time, has nothing to do with the supposed rift - since there is no spat, to begin with. The tipster said that the wife of Prince William was suffering from motion sickness while she was riding the carriage. "The truth is the Duchess of Cambridge gets very seasick and doesn't enjoy the rocking motion of carriages," the unnamed insider stated. "Worrying she may be ill on such an important occasion as Trooping the Colour added to her stress," the same informant added.

There are also reports saying that Kate Middleton had been "disrespectful" to Queen Letizia at the Order of the Garter. The two Royal women met on Tuesday for the said event in London. Some fans think that there was a tension between Prince William's wife and the wife of the King of Spain.

"What did Letizia ever done to Kate? Last time they visited she did the same, ignored her at the State Dinner and put on a grumpy face all night. She was rude not to curtsy," a fan wrote on Twitter about the alleged tension between Kate and Queen Letizia. "Watch the body language - Kate doesn't even acknowledge Letizia," another Royal follower wrote.

Some Twitter users stated, whether or not Kate and Letizia indeed have some sort of tension between them, they would not be surprised since Prince William's wife had been involved in several supposed feuds recently, which include her sister-in-law Meghan Markle and close pal Rose Hanbury. However, body language expert Judi James stated that Kate did not appear friendly during the ride with Letizia since she does not like carriage rides due to her motion sickness. She added that the two Royals did not show signs of close bonding, but it does not mean that they are not on good terms.

"Kate is standing apart from Queen Letizia here, but of the line-up the two women have the most mirrored body language signals, suggesting some shared thinking in terms of royal appearances," Judi said. "Kate's smile looks congruent rather than forced," she added.

The Duchess of Cambridge has yet to comment on these allegations saying that she has an attitude problem. Stay tuned to Business Times for the latest news and updates about Kate Middleton and Prince William!
