Everyone knows there are some things you just don't wanna be called.
Would Allegra Versace want to be called fat? Well, maybe. Okay, bad example.
One can certainly understand, however, why the lovely Hayden Panettiere took issue and flipped out after being mistaken for that whoremonger Lindsay Lohan last night.
TMZ staffers spotted the Heroes cheerleader leaving the Hollywood hotspot L Scorpion last night with co-stars Milo Ventimiglia and Leonard Roberts.
That's when a confused onlooker shouted out, "Give 'em hell, Lindsay!"
When one of the members of the paparazzi reiterated the fan's mistake, a huffy Hayden Panettiere yelled back, "Don't ever call me that again!"
Wow. Lindsay Lohan, you just got owned. Good think Hilary Duff would no longer be as offended under similar circumstances.

After the initial skirmish, the fan didn't hear Hayden clearly and uttered the name of Dina Lohan's daughter yet again! But fortunately, before Hayden could berate the fan a second time, a cameraman screamed a string of choice obscenities to the confused Lohan fan.
No word on whether Rumer Willis was there.
