Jillian Michaels Says She’s Going to Sue Netflix, Bob Harper, Dr. Huizenga Over ‘Biggest Loser’ Doc

Jillian Michaels is coming out swinging — telling TMZ the entire ‘Biggest Loser’ documentary is a giant lie … and she’s already lawyering up.

The celeb trainer says she’s meeting today with powerhouse attorney Bryan Freedman to plot her next move — and that move includes going after Netflix, the producer of the doc, Bob Harper, and Dr. Robert Huizenga.

Jillian isn’t stopping there either … she points out Brandon Riegg — the exec who bought the doc for Netflix — was one of the top dogs at NBC during the last several seasons of “The Biggest Loser.” Translation: he knew exactly what went down BTS.

As for the claims she was sneaking contestants caffeine pills … Jillian tells us that’s bogus, and she’s got the receipts.

She says she’s sitting on numerous emails — several of which she showed in an IG post Tuesday — proving caffeine was always approved on the show — just like Ambien and smokeless tobacco, which she personally refused to use.
