Prince Harry left red-faced as Invictus Games crowd sings ‘Happy Birthday’

No hangovers here!

All eyes were on Prince Harry Friday morning when a large crowd at the Invictus Games sang him “Happy Birthday” as he rang in his 39th year.

The Duke of Sussex appeared red-faced during the celebratory rendition as he and his wife, Meghan Markle, beamed from ear to ear during a volleyball game between host country Germany and Poland.

After he and Markle took their seats, the announcer asked the crowd, “Is there anybody here celebrating their own special occasion today?”

“Anyone’s birthday? Oh, I think it is someone’s birthday. A certain Prince Harry, the Duke of Sussex, is 39 today. Happy birthday! Let’s sing along.”

The announcement left Harry bashful as he thanked the crowd by giving them a thumbs-up and attempting to cheer on an equally shy child he was seated near.

The exiled royal is spending his special day committed to his work by supporting veteran athletes take part in his Invictus Games in Düsseldorf, Germany.

And it seems as though his boozy birthday festivities from the night before didn’t leave the duke with a raging hangover, as the father of two appeared fresh-faced on his big day.

Despite the well wishes, Harry has yet to receive a birthday message from his estranged father, King Charles, or brother, Prince William.

The royal family no longer sends public birthday wishes to non-senior working royals, hence their radio silence on Markle’s 42nd birthday on Aug. 4.

Harry celebrated his birthday Thursday night by wolfing down Germany’s delicacies — literally.

The duke indulged in blood sausages and Wiener Schnitzel at a secret feast at a German brewery called Schumacher in Düsseldorf, where the group drank locally brewed beer and ate traditional food.

Harry knocked back six beers during the celebration, which was also attended by Markle and a dozen of Harry’s aides, according to the eatery’s head waiter Frank Wackers.

Wackers told DailyMail.com that the duo and their party devoured family-style dishes of wiener schnitzel, pork knuckle, sausage, roast, and mashed potatoes.

The father of two was also presented with a white chocolate birthday cake during the meal.

After the feast, Harry and Meghan posed for photos with several excited employees before the duke left staff a hefty tip.

A source close to Harry told the outlet that the group headed back to their nearby hotel “just shy of midnight” to sing him “Happy Birthday” and indulge in cake.
