Fergie was spotted looking incognito (well, as much as she ever can) making her way through LAX yesterday. She bumped into Nicky Hilton outside the airport, which is funny (but definitely not the most random random celeb encounter recently). Over the weekend Fergie hopped up to Seattle briefly to play at the Bumbershoot Festival, and then she was back in LA and immediately off to the airport again to catch some of NY Fashion Week. From there, she heads to Vegas for this weekend's MTV VMAs. Talk about an exhausting schedule! Hey, that's the life of a celebrity.
