Lindsay Lohan house arrest partyLindsay Lohan isn't exactly doing a stellar job of making her house arrest stint look like time spent reflecting on her latest indiscretion. The actress threw a roof party on Sunday, letting every paparazzo and tourist with a point-and-shoot capture her blatant disregard for the judge's orders to lay low while staying in.

Lohan hosted a house arrest party on the roof of her Venice Beach pad. Guests indulged in cold beers and wine while Lohan, who wasn't seen partaking in the booze, mingled among her guests, cigarette in hand.

And the party was apparently so epic that it called for a costume change as the night wore on -- Lohan started the day in jean cut-offs and a loose, blue-printed blouse and ended the evening in a revealing, low-cut black dress.
