You can watch it below:
The long awaited festive ad is titled 'Give A Little Love' and is inspired by the public's response to this year's pandemic and the everyday heroes.
It celebrates small acts of kindness and begins with a young boy whose football is stuck in a tree. In a cute gesture, a friend arrives to help him and soon sparks off a chain of events in which each character in the ad pays forward their own act of kindness.
The young boy goes on to help a melting snowman, while the snowman in turn helps a couple with a flat tyre.
Switching between different styles of animation, the couple then go on to deliver shopping to an older, isolating family, who then pay their own kindness forward by cheering up a lonely neighbour nextdoor.
The heartwarming ad perfectly sums up how the country have come together this year and in a touching tribute to Captain Sir Tom Moore, ends with 'Give A Little Love' written in the sky with smoke from World War II spitfire plane.
For the first time in several years, the soundtrack to the ad is an original song, written and performed by Celeste.
Speaking about the ad, Celeste said: "I felt really honoured to be asked to take part. The message that everyone really wanted to get across was the idea if you're kind and giving, then these little acts hopefully can ricochet and make the world a better place."
The ad is aiming to raise £4million for two charities, Home Start and Fare Share, with a further £1million set to be donated by Waitrose and John Lewis branches to help local charities.
But John Lewis explained it almost didn't go ahead. James Bailey, executive director of Waitrose, said: "Each year festive adverts come and go - and some are remembered more vividly than others.
"But our advertising this year will leave a lasting legacy - and in that way we hope it won't just be for Christmas. We did consider whether it was right to produce an ad this year at all.
"However, FareShare and Home-Start told us how much of a difference this campaign could make, both on a financial level and in raising awareness of the incredibly important work they do with families across the UK."
As normal, customers will be able to buy merchandise related to the ad, and 100 per cent of profits will go to charity.
Executive director Pippa Wicks, said: "We recently set out our ambition for our business to be a force for good - so we decided that this year was the year to break the mould and do something different.
"We have a long tradition of helping support the communities which we serve, so as we launch one of the best loved assets, our Christmas ad, it's fitting to take this one step further by working hand in hand with two incredible charities supporting families in need.
"We were humbled by the kindness shown by the British public during the pandemic. We want this campaign to be uplifting and to inspire everyone to give some kindness in their own way this Christmas, especially to those who need it most.
"The pandemic has proved that it's our small acts of love and kindness, particularly in challenging times, that captures what it is to be human; and when one small act of kindness multiplies it can have a lasting impact."
Get the tissues for this one guys, it's a tear jerker!
