Paris Hilton pretty much spends her time flying around in private jets and making scenes in airports.  Today was no different when we spotted the heiress at Heathrow airport in London, with a film crew behind her.  Paris was most likely filming a segment for her bff show which is currently airing on MTV.  So, when do you think P will get knocked up by Benji Madden? That would make for some fantastic reality ("reality").
