The Baywatch actress was to be the star guest at designer Richie Rich's A*Muse show which almost landed in trouble when Anderson's plane was delayed and she arrived three hours late to the event.
"She showed up at 9.55 when the show was supposed to start at 9, and press people were there as early as 7 to interview her. People were yelling at door handlers and getting incredibly antsy, especially because the standing room was so packed," the Daily Express quoted a source as telling the New York Daily News.
"Some guests started storming out at 9.30, when the start of the show was nowhere in sight. They had shut the doors at 8.40 since it was so crowded so there were guests on the street who couldn't get in. They were outraged," the source added.
But the star was said to have made it up to the crowd with a dash of humour, telling reporters she was late after changing outfits at her hotel: "I got dressed-well, semi-dressed - before I got here."
