NBC and producers of hit series The Biggest Loser are saying that longtime trainer Jillian Michaels will not be returning for the show’s 16th season, CBS News reports.

"After helping hundreds of contestants transform their lives and inspiring millions of viewers at home, The Biggest Loser and Jillian Michaels have decided to part ways and she will not be returning for season 16 when it airs in the fall," NBC said in a statement, according to Today.com.

This departure marks Jillian Michaels’ third from the series. The first, in 2006 led to Michaels missing the third season of the series. Then in 2011, Michaels left again, missing seasons 12 and 13 of the show. However, the hard-nosed trainer will still be busy after her departure from the series. Michaels is currently working on a documentary titled Finding Thin, according to CBS News.

CBS News reports that Michaels’ replacement has not yet been announced. The season is slated to premiere on September 11 at 8 p.m., according to Today.com.
