Kristen Stewart at the Met Gala 2013

Kristen Stewart's Met Gala Moments With Sienna, Tom, Cameron, and More

Kristen Stewart, Sienna Miller, and Tom Sturridge at the Met Gala 2013.

Kristen Stewart pulled out a showstopping look when she attended the 2013 Costume Institute Benefit at the Metropolitan Museum of Art in NYC on Monday while wearing a Stella McCartney jumpsuit. Although her boyfriend, Robert Pattinson, didn't join her on the red carpet, she did attend the event with designer Stella and Cameron Diaz by her side. Kristen has attended previous Met Gala parties, and this year's exhibit, Punk: Chaos to Couture, is a fitting one for the famously nonconformist actress. She kept the fun coming through the night as she made her grand exit with pals Sienna Miller and Tom Sturridge.
