Lip reader reveals emotional six-word comment Prince Louis made to Kate Middleton during recent appearance

A lip reader has revealed the six-word comment Prince Louis made to Kate Middleton during their recent family appearance together.

Earlier this month (6 December), the Princess of Wales hosted her fourth annual Together at Christmas concert at Westminster Abbey in London.

She attended the concert with her husband Prince William and their children, Prince George, 11, Princess Charlotte, nine, and six-year-old Prince Louis.

The co-production between The Royal Foundation and BBC Studios Events Productions featured premiere performances from the Westminster Abbey Choir, Paloma Faith, Gregory Porter, JP Cooper, and Olivia Dean, and works to combine traditional and modern elements to appeal to people of all faiths and none.

Speaking ahead of the service, the mum-of-three said: "Christmas is one of my favourite times of the year. It is a time for presents, tinsel and mince pies, but it's also a time to slow down and reflect on the deeper things that connect us all. It is when we stop and take ourselves away from the pressures of daily life that we find the space to live our lives with an open heart, with love, kindness and forgiveness, so much of what the Christmas spirit is all about."

She added: "The Christmas story encourages us to consider the experiences and feelings of others. It also reflects our own vulnerabilities and reminds us of the importance of giving and receiving empathy, as well as just how much we need each other in spite of our differences."

The concert was later aired on Christmas Eve (24 December) on ITV with many wondering exactly what was said between Kate and her youngest child, Louis, during an exchange.

In one clip shared to social media, Kate could be seen looking down at Louis and smiling before he told her: "We're looking out for each other," according to lip reader Nicola Hickling.

Kate's appearance at the Together at Christmas carol service was the Princess' first major return to royal duties following her cancer diagnosis earlier this year, which was followed by rounds of chemotherapy.

She shared the news she was cancer-free a few months back in September.

In a statement shared once she had completed chemotherapy, she said: "The last nine months have been incredibly tough for us as a family. Life as you know it can change in an instant and we have had to find a way to navigate the stormy waters and road unknown.

"The cancer journey is complex, scary and unpredictable for everyone, especially those closest to you. With humility, it also brings you face to face with your own vulnerabilities in a way you have never considered before, and with that, a new perspective on everything.

"This time has above all reminded William and me to reflect and be grateful for the simple yet important things in life, which so many of us often take for granted. Of simply loving and being loved.

"Although I have finished chemotherapy, my path to healing and full recovery is long and I must continue to take each day as it comes," she said, hinting at what's ahead.

"I am however looking forward to being back at work and undertaking a few more public engagements in the coming months when I can. Despite all that has gone before, I enter this new phase of recovery with a renewed sense of hope and appreciation of life."
