Prince William's birthday message to Prince Harry in 2020 vs Prince William's birthday message to Prince Harry in 2021

The short message Prince William shared to mark Prince Harry's 37th birthday on Wednesday the 15th of September shows the brothers still have 'icy' relations, a royal expert has claimed.

This year:

To mark the Duke of Sussex's previous birthdays, the Cambridges social accounts used pictures of William and Harry together. 

In 2020, they picked a picture of William, Kate Middleton, 39 and Harry racing one another during a joint engagement prior to his wedding to Meghan Markle. 

In 2019, they used a snap of the two brothers in uniform, chatting in St George Chapel in Windsor ahead of Harry's 2018 wedding to Meghan.

Whatever! 

Happy birthday Prince Harry!!
