• Prince joined Valiente team as they took on Coca-Cola at National Polo Center
• He cut a low-key figure but arrival was given away by large Netflix film crew
• He and Meghan attended charity game at Grand Champions Polo Club Friday

Prince Harry makes another cameo in the posh world of polo as he huddles with players on the sidelines of a US Open quarterfinal.

The Prince joined the Valiente team behind the scenes as they prepared to take on Coca-Cola at the National Polo Center.

He cut a low-key figure in black jeans and a grey t-shirt – but his arrival was given away by a dozen-strong Netflix film crew who were on hand to shoot his interactions with the awe-struck players.

The Duke of Sussex, 39, has been in Wellington, Florida this weekend filming scenes for his new Netflix show about the genteel world of polo.

He and Meghan were the main attraction Friday afternoon as they attended a charity game at the Royal Salute Polo Challenge at the swank Grand Champions Polo Club.

The couple mingled with spectators and smiled for photos before Harry saddled up to take on a team captained by his dashing Argentine pal, Nacho Figueras.

The carefully choreographed event raised funds for the Sentebale organization which the Prince co-founded in 2006 to help kids battling HIV in Africa.

It was also a chance to begin filming for Harry’s new documentary offering ‘unprecedented access to the world of professional polo’, one of two new projects the Sussexes have in the works.

A camera crew followed the couple’s every move as Harry scored a goal then stepped up the podium to receive the trophy – and a tender kiss from Meghan.

They were back at it Saturday as around a dozen crew members arrived at US National Polo Center to get in position to film a US Open quarterfinal between the Coca-Cola and Valiente teams.

The new show will be produced by Miloš Balać, the Emmy-award winning filmmaker behind the Ryan Reynolds sports doc Welcome to Wrexham.

The Prince was flanked by two guards in plain clothes but looked relaxed and engrossed by the pre-game team talk before the two sides took to the field.

Harry was joined on the sidelines by Nacho, the pair looking on with interest as the crew sent up a drone to get aerial footage of the game.

The Prince was taking a keen interest in the production side of things, watching back segments of the footage on a monitor.

He paused briefly to pet a cute Jack Russell dog and take a video call, passing the phone to Nacho to say hi.

Valiente’s star player, Adolfo Cambiaso, was on Harry’s victorious team for Friday’s charity game.

The Argentine is considered one of the world’s best players.

‘He didn’t say too much. He came to watch and support Cambiaso. They are good friends,’ said a member of the Valiente team.

The score was deadlocked at 5-5 when the Prince left, he and his entourage hopping into a swish black Merecedes SUV before driving away.
