Just as I suspected would happen (and come on, the people at Pure had to see it coming too), Lindsay Lohan has canceled her 21st Birthday Party in Vegas. Lindsay's rep told Us Weekly that Lindsay "is focusing on her recovery 100 percent." Despite excitedly releasing the sordid invitations last week, a rep for Pure says they stand by the starlet's decision:

"We support Lindsay and wish her the best as she is taking care of personal matters at this time. Due to the unique circumstances, as of this afternoon Lindsay's birthday party at PURE Nightclub has been canceled. We think the world of her and look forward to working with her in the future."

At least this gives hope that LL is taking this rehab thing seriously (the second time around), but Lindsay's Vegas going days are far from over. Apparently Pure agreed to let Linds back out on her commitment after she signed a contract and received payment because she agreed to appear at the club at a later point.
