Kate Middleton’s siblings had a good start to the New Year.

Pippa Middleton was photographed frolicking in St. Barts with her husband James Matthews. Pippa, who just gave birth to her first baby last year, showed off her toned physique by wearing a two-piece swimsuit. Pippa was also photographed dipping in the water and holding hands with Matthews.

Prior to the couple’s vacation, Middleton’s younger sister was first seen carrying her 11-week-old baby Arthur on the Caribbean island. The couple was also joined by Matthews’ brother Spencer and his wife, Vogue Williams during the trip.

Meanwhile, Middleton’s brother, James, also spent some quality time with his new girlfriend, whose identity has been exposed. The stunning blonde was photographed relaxing on James’ legs and touching his abs. At one point, James and his new girlfriend were also photographed kissing each other.

The three couples were also photographed together while sitting on a platform with the Eden Rock – St Barth's label on it.

Middleton, Prince William, and their kids didn’t join the couples during their New Year vacation. But before ringing in the New Year, there were rumors that the Duke and Duchess of Cambridge will celebrate the holiday with Middleton’s parents, Michael and Carole Middleton, in Berkshire.

Prince William and Middleton celebrated Christmas with the royal family at Queen Elizabeth II’s Sandringham estate. This is why it only makes sense if they indeed decided to celebrate with Middleton’s side of the family for the New Year.

As of late, it is also unclear where exactly did Prince Harry and Meghan Markle celebrate the New Year. But there are some rumors suggesting that the couple flew out of the United Kingdom to spend quality time with Markle’s mom Doria Ragland.

Prince Charles reportedly spent New Year’s Eve with Camilla Parker Bowles in the Scottish Highlands. Richard Fitzwilliams, a royal commentator told The Sun that the Duke and Duchess of Cornwall typically celebrate on Birkhall on the Balmoral estate in Aberdeenshire because Prince Charles owns it. This is also where Prince Charles and Camilla’s honeymoon took place.
