See Meghan Markle chug beer at Invictus Games: pictures

Chug, Duchess, chug!

Prince Harry and Meghan Markle celebrated the red-headed royal’s 39th birthday on Friday at the Invictus Games in Düsseldorf in the most German fashion — with plenty of booze.

Pictures obtained by The Post show the couple passing a clear pint back and forth as they watched a volleyball final match before the Harry-founded Paralympic-style games come to a close on Saturday.

The birthday boy was captured enthusiastically cheering during the match, so much so that the former “Suits” actress covered her face as her husband celebrated during the match.

The estranged Duke and Duchess of Sussex also hit up a local brewery called Schumacher with some friends on Thursday, where Harry reportedly threw back six beers while Markle enjoyed just one.

Head waiter Frank Wacker, who served the party, told DailyMail.com that the duo splurged on the birthday feast, which apparently included family-style dishes of wiener schnitzel, pork knuckle, sausage, roast, and mashed potatoes.

“They were very happy,” the insider said, adding that Harry received a white chocolate cake for dessert. “He is a lovely man, and they were so nice.”

Body language expert Judi James explained to the Mirror how Harry seemed “bashful” yet happy to celebrate his special day at the beer hall.

Meanwhile, restaurant owner Thea Ungermann claimed the royal’s presence gave her “goosebumps.”

We’re sure the generous tip Harry reportedly left staffers didn’t hurt either.

Harry may have gotten lots of birthday love in Europe, but he doesn’t seem to be getting the same treatment from his family in the United Kingdom.

While the royals usually post a tribute for a family member’s birthday, The Firm most likely won’t share a message on social media this year.

Markle didn’t get a birthday shoutout from the family, either, when she turned 42 on Aug. 4.

The couple famously stepped back as senior members of the family in 2020 and have been living their best life in Montecito, California, ever since — In-N-Out Burger and all.
