Lohan gets testy on escalator ride

altWE HEAR: Lindsay Lohan made quite an impression on at least one White House Correspondents’ Association dinner guest who happened to share an escalator ride with the tabloid fixture ahead of the event at the Washington Hilton…and not in a good way.

Our tipster eyed the flame-haired star shooting daggers and snapping at her assistant, who had apparently stepped on the actress’ black, floor-length gown.

Lohan, 25, was also overheard pining for a cigarette and complaining that there was nowhere in the hotel for her to light up.

When reached for comment about the dress snafu, Lohan’s spokesman, Steve Konig, said, "That is an unbelievably stupid question and we’re not going to dignify it with an answer."
