Get in Bed With Sean Penn

Creative Coalition Gala. Duvet, 45 W. 21st St., nr. Sixth Ave. Hop on a bed with Sean Penn and pretend you're in a little rescue boat with him. He's also winning the Christopher Reeve Award for "unwavering convictions in the face of pressure." Like when he told off Chris Rock for making fun of Jude Law at the Oscars. Oh, and Marcia Gay Harden, Harvey Keitel, and Branford Marsalis will be there too.

Nas Black and White Ball. Capitale, 130 Bowery, nr. Grand St., 9 p.m. Nas drops his new album, Hip Hop Is Dead, with a big party featuring Kanye West, Jay-Z, Kelis, Beyoncé, and Chris Webber. If Truman Capote were alive, he'd be there too.

Children of Men screening. Tribeca Grand Screening Room, 310 W. Broadway, nr. Canal St., 7:30 p.m. Ogle stars Clive Owen and Julianne Moore and director Alfonso Cuarón. Celebrate the holidays with a movie about urban terrorism.
