Sam's Pill

Now this could totally be a multi-vitamin around Sam's neck ... and even if it's not, just because she wears a plastic mold of an illicit drug on her necklace doesn't mean she DOES drugs. Maybe it's an anti-drug message, right? Or is Michael Lohan right about his daughter's Sapphic sister?

Sam DJ'd at Rain at the Palms on Saturday night, alongside Paul Oakenfold. We hear Linds and Sam stayed inside the Fantasy Tower at the casino and resort together, but we saw Lindsay back in LA Sunday morning, so it was a short trip!

We caught them arriving at the hotel on Saturday -- a casino cutie was checking out Lindsay, much to Sam's dismay!
