Julia Roberts, her actress niece Emma Roberts, and more stars stepped out in New York City to join in an evening of charades for a good cause.

The celebs were participating in the Labyrinth Theater Company's Celebrity Charades Benefit sponsored by Entertainment Weekly magazine. The 7th annual event featured four celebrity teams competing in a speed charades competition.

The participants had different approaches when it came to preparing for the big night. Julia Stiles took a laid-back approach, telling ET, "We'll just wing it. As long as I don't trip I'll be ok."

On the other hand, Christopher Meloni won two years ago, lost last year, and this year planned to reclaim his title. On his way in to the event, he told ET, "It's not going to be pretty."

He noted, "Unfortunately, I'm not allowed to play it at home. My wife thinks I get a little too competitive."
