Looks like Lindsay Lohan‘s recent late night exploits have cost her the much-hyped 21st birthday party she was looking forward to throwing in Vegas. Sponsorship for the July 2 bash is disappearing quicker than coke on Blow-han’s coffee table – and now everyone from Pure nightclub, to the Social House restaurant and even vodka company Svedka look to be pulling out. Oh well. She could probably do with a quiet night in anyway.
