Lindsay Lohan Tells Nightclub Crowd To Shut Up

Exclusive Details

Lindsay Lohan's finding out having your name above the door of a nightclub, doesn't mean everyone inside will show you respect ... no matter how much you ssshhh 'em and cuss at 'em.

LiLo jumped into the DJ booth during Saturday night's opening of LOHAN in Athens ... and it did NOT go as she planned. Check out the vid ... Linds sounds like an impatient teacher dealing with a rowdy classroom.

You can tell though ... she's taking this club biz seriously. Sources at LOHAN tell us she pulled an all-nighter -- arriving at 10 PM to make sure everything was ready to go, and stayed until 5 AM.

We're told she was hobnobbing with Greek business owners in VIP, and security stopped fans from snapping pics. If only she could've gotten someone to muzzle the crowd of 2,500 for her announcements.
