HOLLYWOOD - The bosses of Las Vegas club Pure have agreed to halt plans to celebrate Lindsay Lohan's upcoming 21st birthday without the actress.

Lohan called off plans for a two-day July 2 bash at Pure shortly after checking into rehab last month--but club bosses reserved the right to keep advertising the celebration, so that fans could toast the troubled Mean Girls star.

Confirming the party had been cancelled, Lohan's spokesperson released a statement yesterday, in which she said, "The party was cancelled officially over two weeks ago. We were confused why Pure was even still promoting it."

Pure spokeswoman Kate Turner says, "Due to the unique circumstances, Lindsay's birthday party at Pure Nightclub has been cancelled.

"We think the world of her and look forward to working with her in the future. We support Lindsay and wish her the best as she is taking care of personal matters at this time."
