There was celebrity horse play going on both sides of the pond this weekend.

In the states the rich and famous flocked to the Kentucky Derby, while in London's Coworth Park, Oscar-winner Charlize Theron was front-and-center for a polo match featuring Prince Harry.

The blonde South African-born beauty was seen chatting it up with England's most eligible bachelor in these just-released pics.

The match was a charity event for Foundation of Prince William and Prince Harry.
