The rapper - real name Tracy Marrow - announced the news via Twitter earlier today, stating that he will star in the series for the coming two years.
"I've just locked in my new SVU deal," Ice-T wrote. "So I'll officially be back for the next 2 years at least. DONE. (sic)."
It was announced in late May that Law & Order: SVU star Chris Meloni had left the NBC series. Meloni played Detective Elliot Stabler since Law & Order: SVU premiered in 1999.
Meloni's co-star Mariska Hargitay has admitted that she will "miss" Meloni when she starts shooting the upcoming season of the popular crime drama.
Hargitay will have a reduced role in the 13th season of Law & Order: SVU. According to Deadline, the show is considering a female partner for the actress now that Meloni has departed the series.
Jennifer Love Hewitt was rumoured to be in talks for a part on Law & Order: SVU, but negotiations with the actress have reportedly fallen through.
Law & Order: Special Victims Unit will air Wednesdays at 10pm on NBC in the fall.
