The actress, 52, posted a photo on her Instagram alongside Mariska Hargitay in a behind the scenes moment.

“Back to work! In deep discussion with @therealmariskahargitay #BTS,” Shields wrote in the caption.

Not much is known about what character Shields might play, other than the network 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 two-time Golden Globe nominee noted in a statement. “I’m excited to stir the SVU pot a bit.”
