Maria Bello has signed on to appear on Law & Order: SVU, TVGuide.com has learned exclusively.

The Golden Globe- and SAG-nominated actress (A History of Violence, The Cooler) will appear in two episodes, playing a woman with a secret past that Detective Benson is investigating, according to a source close to the production.

It's also a reunion of sorts for Bello and SVU executive producer Neal Baer, who worked together on ER. Her episodes have not been scheduled.
