A.J. Cook is heading back to 'Criminal Minds.'

After being let go from the series, Cook will return to the CBS drama for one episode this spring.

According to TVLine, Cook will return to set this week.

Fans mounted online campaigns in support of Cook and her character, J.J., but the only result was a two-episode swan song earlier this season.

UPDATE: Cook took to Twitter to confirm the news. She's returning for Paget Brewster's final episode of the CBS series.
