Mariska Hargitay: Joyful Heart Gala with Hilary Swank!

Mariska Hargitay and Hilary Swank attend the 2011 Joyful Heart Foundation Gala on Tuesday (May 17) at the Museum of Modern Art in NYC.

The 47-year-old Law & Order: SVU star wore a Carolina Herrera dress, while Hilary, 36, stepped out in Oscar de la Renta.

Mariska hit the red carpet with husband Peter Hermann and also met up with pals Alec Baldwin and Hugh Jackman.

FYI: Mariska founded the Joyful Heart Foundation in 2004 to help survivors of sexual assault.
