The Mean Girls star hit the headlines last week (begs12Sep11) following accusations she tossed a drink over a photographer at a V Magazine bash for New York Fashion Week on Wednesday (14Sep11).
Stunned eyewitnesses took to their Twitter.com blogs to recount the reported incident with snapper Jasper Rischen, who himself tweeted, ""Wow. Lindsay Lohan is as trashy as they always say. She threw drinks and glasses to me as we tried to take a shot for V magazine.""
And Lohan is back in the gossip columns once again - she was said to be an uninvited guest at an afterparty for designer Jacobs at Manhattan's Dream Downtown hotel on Thursday.
According to the New York Post's Page Six column, she and her friends were initially refused entry to the Top of the Standard venue, before a member of her entourage called in a favour from the hotel's owner Vikram Chatwal, who arrived to walk Lohan and her pals into the event in person.
But the drama continued soon afterwards, when security guards approached Lohan and allegedly told her she was not welcome at the party - prompting the embattled actress to leave and head to another fashion event nearby.
A representative for the star refused to comment on the reports, insisting he had ""no knowledge of either of these incidents"" as he was ""unable to reach Lohan for clarification"".
