This is why everyone thinks Lindsay Lohan is still very much on drugs.

According to new reports, Lindsay was good “friends” with Nick Prugo, the 18 year-old drug user that has been arrested for robbing both Lilo and Audrina Patridge.

Not only was Lindsay friends with dude, he was seen on the set of her last paying job…the straight to DVD movie Labor Pains.

One source even claims that they saw the two together on at least 10 different occasions. We’re all thinking it…should I say it? Should I?

Maybe I’ll just say that all drug users should remember to pay their dealers or they just might end up getting burgled.

Word around the gossip-phere is that kid is allegedly into cocaine…and that Lilo has moved on to the ever more glamorous meth… of course this is all just rumor and speculation…but if it quacks like a duck then that duck just might be a tweeker.
