The duo teamed up Sunday during the second day of playing at the Audi Polo Challenge at Coworth Park Polo Club in Ascot, England, dressed in gray and white team shirts and sporting matching helmets, mallets and footwear.
While Sunday’s match saw no sign of either Princess Kate or Meghan Markle, the latter was snapped cheering on her royal boyfriend Saturday as he played to support his charities Sentebale and WellChild.

On Saturday, Kensington Palace tweeted that Harry, 32, and William, 35, will participate in polo games throughout the summer to support their charities, as they’ve done annually since 2007. The brothers have, to date, raised over £10 million for charitable causes, the palace said.
Although Markle and Harry have been photographed together in the past, the appearance of the Suits star, 35, at Saturday’s match — which was also attended by William’s former Eton College classmate Eddie Redmayne — marked the first public event the couple have officially attended as a pair.

It seems like the second official appearance the couple may make together will be surrounding the May 20 nuptials of Kate’s sister Pippa Middleton. Markle will attend the evening reception as Harry’s date, as PEOPLE previously reported.
“Despite the distance, the media attention and everything else, there’s a real ease to their relationship,” a source recently told PEOPLE of the pair. “It just works. They are deeply happy.”
