Prince Harry was escorted into the Silverstone arena for the British Grand Prix in Northhampton this afternoon. He was on hand to watch the races with the Walking With the Wounded organization, and they got a behind-the-scenes look at the action from Red Bull Team boss Christian Horner. Harry posed for photos with a few drivers, including Formula One racer Jenson Button, who used to date model Florence Brudenell-Bruce. Prince Harry was linked to Florence last month after he and longtime girlfriend Chelsy Davy called it quits, though it looks like Harry and Jenson were happy to stand next to each other for the cameras. Harry is hanging out in the UK while his brother Prince William and Kate Middleton tour California. The royal couple is attending a few final events in LA before heading back to London later this afternoon.
