The Duchess of Cambridge has revealed Prince Louis’ favourite song (and it’s a classic)

Well, his big day IS coming up next month.

It seems little Prince Louis, who is turning two next month on April 23rd, has one special thing he will be excited about once his birthday rolls around. According to his mum, the good, old Happy Birthday song is Louis' very favourite song, which, you know, will make his celebrations extra special no doubt, when everyone will be singing it to him as he opens his presents and eats his birthday cake. Speaking to HELLO! at the reception in Buckingham Palace celebrating the 25th birthday of Place2Be, a mental health charity that supports children and young people, the Duchess of Cambridge wished two of the choir members a happy birthday, before joking that it ought to be her singing to them instead. The mum-of-three then went on to share that the classic Happy Birthday tune is in fact 'one of [Prince] Louis's favourite songs'. How cute is that?! Kate has had a busy few days of late, between reuniting with her brother-in-law and his wife Meghan at the Commonwealth Day service, before rushing over to Buckingham Palace to host the 25th birthday celebrations of Place2Be.

Posting about the event on their shared official Instagram account, @KensingtonRoyal, Kate captioned a short video of the night with:

'Happy 25th Birthday @_place2be — here’s to many more! The Duchess of Cambridge, Patron since 2013, hosted a reception at Buckingham Palace to celebrate the charity’s incredible work over the past 25 years.

'No child or young person should have to face mental health problems alone — and that has been the founding mission of Place2Be, whose teams across the UK have provided mental health services in schools.' Speaking at this evening’s reception, The Duchess said: 'Having visited many of your schools, meeting hundreds of your wonderful staff, children and young people, it is heart-warming to see that the support you provide is so much more than just being there in a time of desperate need'.
