Lindsay Lohan Birthday Punch (PHOTOS, VIDEO)

Lindsay Lohan celebrated a sober 24th birthday at L.A. hot spot Voyeur.  She got more than she bargained for according to a 'tweet' that she sent at 1:00 a.m.  It said: "A waitress just hit me - punched me for no reason."

Lohan was reportedly hanging with Paris Hilton's former flame Doug Reinhardt.  It turns out the waitress in question also has some history with the guy.  She apparently got jealous and popped Lindsay. Ha!

The photo above shows the celeb after the alleged altercation and dare we suggest -- she looks like she escaped unscathed.  Providing chauffeuring duties was her new handler and BFF Eliat Anschel.

Happy Birthday Lilo!
