According to TVGasm and reported by Defamer,  it's blow. Apparently someone in her posse spilled the beans that it's, â€œItâ€™s cocaine and diet pills." Not that many will be shocked, but this is not going to be good for her career - especially since the source continued on to say â€œSheâ€™s gone from occasional coke use to a full on fiend; itâ€™s scary." Her new nickname apparently is Blowhan. And the poor thing is only 19.... she is making her way for an E! True Hollywood story by 20.
Defamer  also has more on Lindsay's MTV after party and others who were denied at the door (sorry Kirsten, but I like your ex-boyfriend so I don't want you here, Dunst along with the Simpson sisters). And she somehow got Nicole Richie and Paris in the same room - but in opposite corners. Check out Defamer for more.
