Michaels, currently featured on ABC's "The Biggest Loser" will join the daytime series under a multi-year deal and also become a special correspondent on lifestyle issues on "Dr. Phil."
"Jillian Michaels is the perfect addition to 'The Doctors' team," said Phil McGraw, the TV psychologist who is also one of the creators of the series. "She not only embraces our mission to supply viewers with critical information to make informed and intelligent health care decisions, but more importantly, she leads by example."
Michaels said in a written statement she was excited with her new gig.
"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," she said.
