Olivia PALERMO not all that SYMPATHETIC to her NEIGHBORS fire!

FAUX-cialite Olivia Palermo spent last week complaining to media outlets that "The City" producers edited her to be a bitch - and she's really sweet in real life. Tell that to her neighbors. On Thursday, a source who was in the lobby of Palermo's TriBeCa apartment building called us and said, "A girl was sobbing in the lobby because a fire had started in her apartment. There were dozens of firemen in the lobby and trucks outside and everything, and neighbors were gathered, trying to comfort the girl. Then, Olivia walks in with her Prada bag and huge sunglasses, completely oblivious to the madness going on. She just struts past the crying girl, the throngs of fire men, and goes upstairs." But Palermo's rep tells us, "She did wait until the firemen told her it was safe to go up, and she took the stairs."

Seriously, what was Olivia supposed to do, give me a break!
