Lindsay Lohan may have claimed to be alcohol free but a new video footage has emerged which suggest that Hohan is still drinking.

Lohan was caught by a hidden surveillance camera at Lotus Nightclub in Washington, D.C. last month topping up her glass of Red Bull with vodka while GF Samantha Ronson DJed.

Last year Bihan completed a 45-day rehab program and we though SamAn was supposed to keep Lindsay on the straight and narrow.

Maybe Michael Lohan was right when he said SamAn was a bad influence.
