Prince William left Kate Middleton in tears after cancelling their New Year plans, one book has revealed.
Back in 2006, when the couple were seeing each other, they had plans to see in the new year together.
Christmas Day for Prince William was spent with the royal family at Sandringham, with plans to travel to Kate to spend the New Year with the Middletons.
However, according to a book, Kate was left in tears when William cancelled his plans at the last minute, which left her fearing for the future of the relationship.
In royal author Katie Nicholl’s 2011 book, The Making of a Royal Romance, she claims William had promised Kate he would join her family but decided to stay with his family instead - informing her by phone on December 26.
Katie writes: "William had been having second thoughts and sat down with his father and his grandmother to have a frank discussion about his future with Kate. Both advised him not to hurry into anything.”
Just weeks later in 2007, Kate and William briefly split and sources later said the Queen was disappointed by the break-up.
The split seemed to be short-lived, with William and Kate seen kissing at an army party at barracks in Bovington, Dorset, weeks later.
And in July 2007, Kate and her brother James were seen at the Concert for Diana, held at Wembley to mark 10 years since William’s mother Princess Diana's death.
It wasn’t long before their romance was confirmed to be back on, and Kate moved into William’s Clarence House flat, where he would return from military duties on Friday nights for weekends together - and the rest, they say, is history.
The Mirror UK reports that Kate and William spent Christmas this year at their country retreat Anmer Hall with their three children Prince George, Princess Charlotte and Prince Louis.
They were joined by members of Kate’s family.

At some point over the festive period, they will visit the Queen, who is spending Christmas at Windsor Castle after cancelling her annual trip to Sandringham.
It's unknown exactly what the children got for Christmas, but according to royal expert Katie Nicholl, Kate is mindful not to lavish extravagant tech gifts on her three children.
That's because she'd reportedly prefer to get them practical presents so they don't end up having too much screen time at once.
