The "Biggest Loser" trainer will also serve as a correspondent on "Dr. Phil."

Jillian Michaels has signed a multiyear deal that will see The Biggest Loser trainer join The Doctors as a co-host next season.

In addition, Michaels will become a special correspondent on Dr. Phil, which like Doctors, is produced by CBS TV Distribution.

She has appeared several times on Dr. Phil spinoff The Doctors, which is hosted by Drs. Travis Stork, Jim Sears, Lisa Masterson and Drew Ordon.

“This is literally the most informative show in daytime, and it allows me to continue to educate people on how to make powerful health choices enabling them to take control of not only their physical well-being, but every facet of their lives," Michaels said. "I have thoroughly enjoyed the time I have spent as a guest on the show and becoming a permanent member of the team makes today one of the best yet.”

Michaels will focus on wellness, prevention and lifestyle dynamics in addition to other health-related issues, producers said.

Michaels announced in December that she'd be leaving The Biggest Loser at the end of Season 11 to take a year off and focus on becoming a mom and doing more charity work.
