Is there another budding royal romance ongoing with the Middletons? Several reports have suggested that Kate Middleton's sister Pippa and her husband's brother Prince Harry are dating and even hiding their secret royal romance. Rumors also claimed that the rift between the Middleton siblings has intensified as their mom Carole tries to manipulate another royal marriage.

There have been several reports in the past claiming that Pippa Middleton and Prince Harry were an item. And now, the rumors have re-emerged after the two were photographed at the airport, Celeb Dirty Laundry reported. While Pippa went to St. Barts with her brother James on New Year's Eve, royal watchers wondered where on Earth is Prince Harry? Because there haven't been many sightings of him since Christmas.

While there have been rumors that the Duchess of Cambridge clandestinely hoped Pippa would find love with Harry, unidentified and unconfirmed palace sources said Kate still thinks Chelsy Davy is a more appropriate bride for her brother-in-law. And since the Duchess has quite grown to enjoy the spotlight, having her sister become part of the royal family seemed to be a bad idea because being married to Prince Harry would bring Pippa to royal stardom.

During the holidays, Prince Harry had joined the Middletons when they celebrated Christmas at Sandringham, sparking speculations that he's planning to join his sister-in-law's family on their trip to the Caribbean for a chance to spend some quality time with Pippa. Unfortunately, Starpulse reported that Prince Harry is not yet ready to settle down, telling People that he has still "a lot of things to do" before committing to a long-term relationship.

Meanwhile, as for royal couple Kate Middleton and Prince William, they will be preparing for Prince George's first day of school. It is also a year of many celebrations for the British royals. And it will start with Duchess Kate, as she is set to celebrate her 34th birthday on Saturday. This 2016 is also a big year for Queen Elizabeth II and Princess Charlotte as the Queen is set to celebrate her 90th birthday on April 21 while the princess will be celebrating her first birthday on May 2, People has learned.  

The royal couple also have big travel plans this year. As a matter of fact, the Duke and Duchess of Cambridge are bound to fly to India in the spring for their first joint foreign tour since traveling to New York in December 2013. Prince Harry will also bring his Invictus Games to the United States in May, specifically to Orlando, Florida. This year will also mark as the 40th anniversary of Prince Charles' Prince's Trust.
