Bombshell Pam Anderson’s three hour lateness turns designer Richie Rich fashion week show riotous.

The former Baywatch beauty and sex tape goddess who is designer Rich’s inspiration for his new line of bizarro sexy boy toy fashions arrived nearly three hours late to a carefully choreographer catwalk du jour.

The A*Muse show which was packed at Amnesia in Manhattan north of the infamous meat-packing district was delayed and one witness told the NY Daily News of the madness.

"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," a spy told the tab. "People were yelling at door handlers and getting incredibly antsy, especially because the standing room was so packed.

"Some guests started storming out at 9:30, when the start of the show was nowhere in sight," the source added that the chaos outside the Chelsea hot spot was even worse.

"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."

But Pam had an excuse – a damn good one – her flight was delayed and she insisted on going to her hotel instead of jetting to the ballyhooed event.

"I got dressed — well, semi-dressed — before I got here," the buxom beauty confessed.

Rich, who held the opening until the arrival of his queen starlet, admitted, "It was a crunch."
