Los Angeles: Troubled star Lindsay Lohan has alleged that she was assaulted by a waitress "for no reason" while she was partying at a club.
The `Mean Girls` star, who turned 24 yesterday, said that she was enjoying a night out at an eatery when suddenly one of the staff members turned hostile.
"A waitress just hit me - punched me for no reason," Lohan posted on micro-blogging site Twitter.
Lohan was partying with friends including Paris Hilton`s ex-boyfriend Doug Reinhardt and Brit rugby player Danny Cipriani, when the incident allegedly took place, reported a news website.
But the club worker, Jasmine Waltz, has spoken denied the allegations, branding Lohan a "train wreck".
"All I have to say is that disturbed little train wreck is delusional. I didn`t hit her. But I`d like too."
Lohan, who is still wearing an alcohol monitoring SCRAM ankle bracelet as her punishment after DUI arrest- is not planning any wild night with friends due to her current situation.
"I mean there`s not much you can do with a monitoring bracelet and no money," her friend said.
The alleged assault and already ongoing probation with no birthday celebration, has further grieved the actress who begun her 24th year at a problematic note.
Earlier this week, Lohan was sued for USD 16,000 over the accusal of premeditated fraud and unpaid bills by an upmarket Los Angeles boutique for her free shopping sprees between November 2009 and February 2010.
