Lindsay Lohan Goes Brunette for Haiti Benefit

Starlet reveals humanitarian side and new 'do at a private party for earthquake relief

Lindsay Lohan has gone back to the dark side!

The actress ditched her blond locks for a new look, which she debuted Wednesday night at an Edeyo benefit event held at Ron Burkle's Beverly Hills estate.

The charity bash for Haiti was hosted by Mark Wahlberg and Ben Silverman and brought out an eclectic assortment of VIP guests like Jeremy Piven, Fred Durst, Busta Rhymes, David Spade and Mayor Antonio Villaraigosa, in addition to L.L.

So is Lindsay having more fun as a brunette?

It's probably too soon to tell. A source tells E! News that LiLo, who sipped on a Patrón cocktail at the fete, arrived late.

But it seems like the newly minted humanitarian had a good time. "Thank you to Ron Berkle and Unik for gathering together last night to raise funds, and awareness for those suffering in Haiti. It was lovely and i was honored to be a part of it," she twittered.

In addition to the top-shelf tequila, guests enjoyed catering from Philippe restaurant and Crumbs cupcakes.
