When your husband is the heir to the British throne, you'd assume an event like your 37th birthday wouldn't be taken lightly. In the case of Kate Middleton, the royal celebrated this year's milestone in royal style hosting not one, but two separate birthday parties.
On the royal's actual birthday - January 9 - the Duchess of Cambridge decided to spend the day at home in Kensington Palace with her children.
According to Vanity Fair, Kate, Prince George, Princess Charlotte and Prince Louis all spent the day having a tea party.
"Kate’s not into big birthday celebrations," a source told the publication. "But George and Charlotte adore birthday cake, so there will be a special tea party at the palace with candles and presents."
