Kelly Giddish is saying goodbye to "Law & Order: SVU" after more than a decade.

The actress, who plays Detective Amanda Rollins on the NBC series, confirmed that the 24th season will be her last. She made her debut in 2007.

"I wanted to address the chatter I've seen online and let everyone know that this will, indeed, be my last season on ‘Law & Order: SVU,’" the 42-year-old began her Instagram post on Wednesday.

"Playing Rollins has been one of the greatest joys and privileges of my life," the star shared. "I've been so fortunate to be a part of the ‘Law & Order’ family for the last 12 years. There is simply no other character on TV like Rollins. She's grown and changed, and I have as well. I started on this show when I was in my late 20s, and I'm grateful I got to spend so many of my adult years with Rollins in my life."

"I'm so excited to take all the things I have learned in my time on ‘SVU’ and put them toward everything that's next to come."

She is expected to depart during the first half of the season, TV Line reported.
