Lindsay Lohan had gone, like, a whole month without getting arrested. Until now.

Lindsay was picked up by New York City cops just a couple hours ago (Thursday) after allegedly punching a woman at a nightclub. Apparently she got into it with someone sitting at an adjoining booth, at one point saying something to the effect of "Give me some space." It looked like things had calmed down when Lindz threw the alleged punch.

This could spell even more trouble for Lindsay, who's already in hot water for allegedly lying about that car crash in California. This arrest could trigger yet another violation of her probation. As of right now, she's still in police custody.
