This year, reality TVโs first family did away with their traditional style of Christmas card and instead left it up to the adorable next generation of North West, Penelope, Mason and Reign Disick to bring the festive cheer. The only tot missing was Saint West, who was born on December 5.

Kensington Palace made all our Christmas wishes come true by sharing our favourite ginger-haired Princeโs card. โMerry Christmas from Prince Harry! Hereโs his Christmas card photo showing one of his favourite moments from 2015.โ The black-and-white photo is of Harry with 95-year-old Tom Neil, the last surviving Royal Air Force pilot from the Battle of Britain took place on Harryโs 31st birthday on Sept. 15. The birthday boy gave up his seat on a spitfire plane for Tom, so that the veteran could take part in a special flypast to celebrate the Battle of Britainโs 75th anniversary.

โHeโs a lovely man. He came and welcomed me back. He was so keen, so welcoming,โ a chuffed Tom explained about Prince Harry.

The Monaco Royal family have released their first family-of-four Christmas card.

Princess Charlene and Prince Albert of Monaco opted for a glamorous portrait. One-year-old twins, Prince Jacques and Princess Gabriella, posed for American photographer Christopher Morris in front of a roaring fire, at their Roc Agel retreat. The highlight of the snap has to be little Gabriella munching on an apple!

On the 25th of December, without fail, The Queen recaps on the year that was in her stirring and iconic Christmas speech.

The tradition was started by father, King George. Here, the Queen smiles at her husband Prince Philip shortly after delivering her first ever Christmas speech in 1957.

Prince Charles and his wife, the Duchess of Cornwall, chose this loved-up snap for last yearโs Christmas card.
Aww, Prince Charles and his wife of ten years, Camilla, the Duchess of Cornwall, have released this gorgeous snap for their 2015 Christmas card.

The loving image was taken during the pairโs summer holiday in Scotland with the simple message, โWishing you a very Happy Christmas and New Yearโ inscribed on the inside.

One of the best royal festive shot, apart from George and his amazing cheeks, is this family pic shot by Jason Bell. Eight-month-old George looks blissfully content in the arms of Duchess Catherine while pup Lupo and dad William watch on.

It doesnโt get much better than Prince Harry in a Santa hat. In 2012, Harry spent some time abroad in Afghanistan with the military. Earlier this year, he announced his retirement from the services.

Her 1994 classic All I Want For Christmas Is You still stands the test of time. No yuletide playlist is complete without it!

Before he was all bleached hair and Skrillex beats, a baby-faced Bieber just wanted to sing you carols and hang out with Disneyโs Pluto.
