While little is known about what character Shields, 52, might play, the NBC described her as one “that will shake up Benson’s (Mariska Hargitay) world this season.”
“I play a very different character from any I have ever played,” the actress noted in a statement. “I’m excited to stir the SVU pot a bit.”
This isn't the first time Shields has worked in the Law and Order family. In 2006, she guest-starred on Criminal Intent in the season 6 episode “Siren Call” as Kelly Sloane-Raines.
Most recently, Shields has acted on popular shows like Scream Queens, Nightcap, and The Middle.
Season 19 of Law and Order: SVU premieres Wednesday, Sept. 27 at 9 p.m. ET on NBC.
