Prince George turned 9 this week.

Prince William and Kate Middleton won't spoil Prince George on his birthday, a source has revealed. George turned 9 years old on July 22nd, but the royal parents did not splash out too much for his special day. Royal expert Kate Nicholl told OK! that his birthday celebrations will be pretty normal. The Cambridges tend to have low-key celebrations for their children, but Kate will make sure it is still special. "George’s birthday falls in the school holidays so I would imagine it will be celebrated at Anmer Hall. "In keeping with past birthdays, it’s usually spent with friends and family and is a pretty low-key affair." "Kate bakes a cake and they have people round to the house. There’s a focus on just being at home with those nearest and dearest," she shared. "They aren’t spoilt with presents, they never go over the top but George will have had a wish list. The young prince had "lots of lovely presents to open up on his birthday". Ahead of Prince George's birthday, Kate and William released a birthday portrait of their son. The photo was taken by The Duchess of Cambridge on a recent family holiday in the UK. "The Duke and Duchess of Cambridge are delighted to share a new photograph of Prince George ahead of his ninth birthday tomorrow." Fans couldn't help but point out the resemblance between Prince George and Prince William after they shared the photo.
