Prince Harry seemed “happy” and appeared to be “enjoying his life” in LA during his latest appearance at a charity tennis tournament last weekend, a body language expert has claimed.

The Duke of Sussex stepped out with his wife, Meghan Markle, in sunny California to attend the George Zajfen Tennis Tournament on Saturday, just one day before his 40th birthday.

Saturday’s event was organised by the Alliance for Children’s Rights in honour of Kelly McKee Zajfen’s – one of Meghan’s close friends – late son, George, who passed away a couple of years ago.

Harry was all smiles as he chatted with the organisers and took pictures with them.

Now body language expert Darren Stanton analysed the duke’s appearance and claimed that Harry showed “real expressions of happiness and joy” with no fake smiles present, which were similar to how he normally acts during the Invictus Games.

Speaking on behalf of Betfair Slots, Mr Stanton said: “Harry looks in his element, he looks really relaxed. He was even doing a little dance at one point.

“He’s got the same sort of facial expressions he has when he’s doing the Invictus Games.

“He seems really happy, with genuine smiles and a state of joy to be involved and to be attending. It’s really positive, he seems to be really enjoying his life and having fun.”

The body language expert added that the prince “doesn’t hide his emotions that well” and during Saturday’s event there were no “red flags” to suggest that he isn’t “completely happy”.

He explained: “From a facial perspective, Harry doesn’t hide his emotions that well.

“When he’s not happy, he tends to have lines on his foreheads – like stress lines. His face also tends to flush red when he is nervous or deep in thought.

“Here, however, we see him in a really calm, relaxed state. That’s a real expression of happiness and joy, as opposed to him just faking a smile.

“When he’s comfortable, he makes lots of open palm gestures, such as here, where he’s giving someone a hug. If he wasn’t relaxed and happy, his hands would be in his pockets, or he’d avoid eye contact, but he’s giving good eye contact with all the people around him and seems really engaged.

“There are no red flags here to suggest he isn’t completely happy.”
