David Beckham was already on the go at Heathrow this morning after a quick stop in London to watch as the English soccer team beat Mexico in a pre-World Cup match last night. His layover was on the way back from his weekend visiting the British troops in Afghanistan on a morale-boosting trip. While David has been abroad, his three sons stayed behind in LA with Victoria. Their oldest son, Brooklyn, stood in for David last night at Victoria and Eva Longoria's LG party, where he rubbed shoulders with some of her friends like Jessica Simpson and Rachel Zoe.
