Lindsay Lohan may be in rehab, but her 21st birthday party plans are powering on without her -- Pure nightclub is making damn sure of it. The party was supposedly at one point sponsored by Svedka Vodka, but the beverage company denies ever signing on for the event. What, you don't want your brand associated with a party celebrating a starlet becoming legal to drink, which takes place only days after said starlet gets out of REHAB for, among other things, underage drinking? I can't see the problem there (note: sarcasm). Today, Pure released this invitation to the event on their website showing, what else, photos of Lindsay with a cigarette dangling from her lips collaged with some personal pics (in which she looks kinda wasted). This whole party, especially if Lindsay doesn't bail which I think she still might, just reeks of bad idea already.
