For three years in a row, Kate Middleton has taken on the responsibility of hosting the annual Christmas carol concert held at Westminster Abbey, and now, it looks like the latest event has been another success — and she had all three of her children there cheering her on. Prince George, Princess Charlotte, and Prince Louis were all on hand to support their mom on her big night, and they all looked perfectly festive for the occasion.

Kate has been counting down to the carol service for weeks.
Considering how much the royal family seems to love the Christmas holidays, it's no surprise that hosting these concerts has become a tradition that Kate holds dear. The event was held on Tuesday and will be televised on Christmas Eve during a special called Royal Carols: Together at Christmas on ITV.
All three of her children attended the event.

Although Princess Charlotte and Prince George have attended the concert every year, this is only the second time that Prince Louis has been able to go — likely because his parents were waiting for him to be old enough to really handle it!
Both Charlotte and Louis dressed warmly in coats, and George wore a suit similar to Prince William's ensemble.
Kate used the moment to draw attention to one of her favorite causes.
"Tonight's carol service with @earlychildhood is a moment to thank all those who work to support babies, young children and families in our communities across the UK, celebrating the golden opportunity that the birth of a new baby brings," Will and Kate shared in a post on their official Instagram account. "Look out for our special postbox which will whisk letters and Christmas messages from our congregation to children who might be struggling this year."

Other members of her family also joined Kate at the concert.

Kate's sister, Pippa Middleton, attended with husband James Matthews as her date, and so did their parents, Carole and Michael Middleton.
And among the royal family members, Princess Beatrice and Princess Eugenie were there, along with Sophie, Duchess of Edinburgh, Zara Tindall, and Peter Phillips.
The concert included performances from Adam Lambert, James Bay, and more.
It looks like Kate can chalk this one up as another win.

It can't be easy being in charge of a big event like this one, but somehow, Kate always seems to pull these things off flawlessly. We're sure that George, Charlotte, and Louis loved the night out — especially because they probably got to stay up past their bedtimes!
