Lohan punched by waitress on her birthday

It's not a happy 24th birthday for actress Lindsay Lohan.
Reportedly, Lindsay Lohan was punched by a waitress at L.A. club Voyeur early Friday morning on her 24th birthday.

The informationregarding the mishap came from Lohan herself.

"A waitress just hit me - punched me for no reason," the actress Twittered around 1 a.m. PT.

A witness tells UsMagazine.com that Lohan — who sipped Red Bulls and hid her SCRAM bracelet with thigh-high boots,  wasn't exaggerating.

"The waitress has a history with Doug Reinhardt, and Lohan was hanging out with him. She was jealous, and out of nowhere, the waitress punched her in the face!" the insider tells Us. "Doug didn't want any part of it and went to the other side of the booth. Lohan ran out."

However the  night didn't improve from there.

Lohan went to a party along  Rockstar House, and voila! ran into the waitress again!
