Aww Niall.

The Mullingar native really pulled out all the stops this year for Children In Need. Children in Need is a UK charity run by the BBC. They raise money throughout the year to help disadvantaged children and young people in the UK with the hopes of helping them further their education and aspirations.

Every year various celebrities help out with the charity, fundraising and organising special events. This year, Niall rallied together a bunch of famous faces including Pixie Lott and Harry Judd to go surprise a bunch of young carers enjoying a day out together along with some of the kids this charity helps. Niall recorded a special message apologising that he too couldn't be there but that he hoped they would have the best day ever. The children were absolutely delighted with all the activities which were set out for them. Little did they know that later on Niall would make a surprise arrival, appearing from behind a curtain to perform for the group. By surprising them, he created the greatest ending to an already remarkable day for this bunch of kids and carers who look up to Niall as their idol. You can check out the clip here: This truly warmed my heart, as did for the heart's of those on Twitter.

Actually don’t think many things have melted my heart as much as Niall Horan on Children In Need. Truly beautiful man ❤️

Niall Horan is 100% the best member of one direction, he actually shows he genuinely cares about his fans and not just the money he earns, he’s amazing. #ChildrenInNeed
