Lindsay Lohan earrings leather jacket boots skirtlindsayearrings.jpg

With Samantha spinning in Vegas (and no one to stalk), Lindsay headed to the Troubadour last night to take in the electro-pop duo La Roux!

Lilo showed off an impressive row of bling in her ear (did she always have so many piercings?) as she left Cadillac at home for a night on the town.

What kind of dog-sitter leaves the pooch at home to go partying all night?

Who we kidding - we're sure one of Lindsay's "assistants" was on hand to scoop the poop.
