Looks like Lindsay Lohan didn't want anyone to see her sexy French maid costume Saturday night!

The actress partied in Hollywood for Halloween, where we snapped shots of her in a classic maid's outfit -- with a sexy twist.

If we may, we must say Linds' legs look amazing! Tres magnifique!

And guess who Linds was partying at the same spot with? Old pal Paris Hilton! Both were at The Roosevelt Hotel.

Linds also spent some time Tweeting back to her fans, and a few haters -- including Jimmy Fallon! See what she said to Jimmy after the jump ...
