Lindsay Lohan has cancelled her birthday party, scheduled for July 2nd at Pure nightclub in Las Vegas. The reason: to focus on rehab. What a crazy concept!

Actually, her rep is saying she officially put an end to the plans a couple of weeks ago:

“The party was canceled officially over 2 weeks ago. We were confused why PURE was even still promoting it.”

Um, because they’re just as big famewhores as your client? Just a guess. And, of course, the club being the generous folks that they are let Lindz out of her contractually obligated party. Naturally not without strings: she’ll have to make a future appearance. Because everyone wants Trainwreck. Maybe they’ll even get lucky and that future appearance will include a future wagon-falling.x`
