Happy birthday,Quaxs Prince Harry!

The famous "spare" celebrated his 39th birthday with wife Duchess Meghan by his side at the Invictus Games in Germany. Video from The Telegraph shows fans singing along for the prince's birthday in the stands.

"From all of us at the @InvictusGamesDE, a heartfelt HAPPY BIRTHDAY to the founder and patron of @WeAreInvictus, Prince Harry, The Duke of Sussex," according to a post on the Invictus X (the website formally known as Twitter) account. "You've given hope, inspired millions and never stop putting a smile on peoples faces."

This is the sixth iteration of the games, the goal of which "is to give soldiers who are wounded, injured or ill in body and soul a greater awareness and recognition in society and to support their path in rehabilitation," according to its website. Harry created the games following his deployment in Afghanistan and attending the US Warrior Games in 2013.

Harry and Meghan share two children together: Archie, 4, and Lilibet, 2. It's been a tumultuous couple of years for the couple since stepping away from senior roles within the royal family, amid media lawsuits, the death of Harry's grandmother Queen Elizabeth II and tabloid fodder.

After he and Meghan stepped down from their roles in the royal family in 2020 and moved to the U.S., Harry reunited with his family for the first time a year later at his grandfather Prince Philip's funeral.

Earlier this year, Harry arrived for his father King Charles III's coronation sans Duchess Meghan, as expected. But somewhat unexpectedly, Harry didn't join his family on the balcony of Buckingham Palace following the ceremony.

Prince William attended the ceremony, as did Princess Kate and their children Prince George, Princess Charlotte and Prince Louis. Harry's attendance marked the first meeting between Charles and his younger son since Harry deepened the rift within the House of Windsor by revealing family secrets in his bestselling book, "Spare.''
