Prince William and Prince Harry are used to being in the media spotlight. As they have grown older, however, there is something else that has become an obsession of the media - their love lives.

When Prince Harry received a medal for his tour in Afghanistan on Monday, his girlfriend Chelsy Davy was in the audience, seated next to his brother Prince William. The British media has been speculating for some time if Harry and Chelsy are on-again or off-again.

The presence of Chelsy at such a formal event will be seen as significant sign by royal watchers. It ranks alongside Prince William's girlfriend, Kate Middleton, attending William's army college graduation. She also attended William's recent "wings" ceremony with the Royal Air Force.

On Sunday, Chelsy and Kate went on a double-date with their royal polo-playing guys . The girls cheered on their boyfriends as the men competed in the Audi polo challenge at Coworth Park, Berkshire.

According to People.com, the two girls sipped champagne during the match while Chelsy, who is a post-graduate student at Leeds University, appeared to have a stack of papers on her knee, as if she was brushing up on some studying.

"They appeared to be getting on really well together," says one onlooker.
