The spare heir tweets!

Prince Harry sent his first-ever tweet yesterday while at an event to promote the upcoming Invictus Games in London. While at the event, the hosts encouraged the Brit to tweet something from their Twitter handle, @InvictusLondon. We know Harry's always up for trying something new -- so he did!

Using an iPad to type, the 29-year-old royal joked and seemed jovial as he tried to compose his tweet before crowd of people. Apparently the red head was typing rather slowly as a host of the event asked, "Are you clear how to do it, sir?" Harry responded with his famous wit, "This is why I joined the army—I can't type properly."

Eventually the newly single royal managed to type out: "Hope everyone will get behind #invictusgames. Great opportunity to support and thank the men and women who have given so much. Harry."

The Invictus Games are an international sporting event that was created for wounded soldiers. The games lasts five days and will be held in London in September. Approximately 300 athletes from 13 countries, including the U.S., Australia, Canada, and Germany, will compete. Sounds like a great cause!
