There are countless reasons to love birthday boy Prince Harry. The second son of Princess Diana and Prince Charles turns 30 today, September 15th. While the royals are celebrating a new baby on the way for William and Kate, they're also celebrating a milestone for everyone's favorite red-haired Prince.

Fresh off the completion of the first-ever Invictus Games, an "international sporting event for wounded, injured and sick Servicemen and women," Harry has lots of reasons to celebrate. The Games were his brainchild, and are supported by the Royal Foundation of the Duke and Duchess of Cambridge and Prince Harry. Working with those who have served their country is a passion of Harry's, and we can't imagine a better means of bringing his passion to life.

Duchess Kate and her sister Pippa Middleton were reportedly planning a pretty special dinner party for Harry's birthday, but had to cancel last minute due to Kate's severe morning sickness. It's now believed that Harry will have a more low-key birthday instead. No matter how he rings in the new year, he'll be getting lots of birthday love today. Because how could you not love Harry?
