Ajay Rochester on Michelle Bridges: "She's a bully."

It’s a celebrity showdown like we’ve never seen before.

Former The Biggest Loser host Ajay Rochester has published a scathing Facebook rant about Australia’s richest fitness guru, Michelle Bridges. 

In the rant, Rochester accused Bridges of stealing every business idea she’s ever had.

Forty-five-year-old Rochester hosted The Biggest Loser with Bridges for four years until she quit in 2009 – she claims there was “incessant bullying” that went on behind the cameras.

Rochester began her Facebook rant after Michelle Bridges was named as one of Australia’s Richest Women, with an estimated net worth of $53 million.

“Trying to get my head around the fact that the woman who bullied me so badly I moved half way around the world to get away from her toxicity and sabotage, was just named on the richest women of Australia list,” she wrote.

“She stole all my business ideas, even took one of my book titles, she made every work day miserable. She spread lies about me until everyone hated me, she leaked bullshit to the media and my bosses until she was top dog and yet “karma” seems to have done nothing but reward her. Seriously question myself on days like today. I’ve given so much to so many and yet I have nothing to show for it. The world is a strange place.”

Rochester went on to write that Bridges would stand outside her dressing room and call her names, leak “bullshit stories” to news outlets and made her life hell.

Aside from the money, the feud comes from a claim Rochester has made that Bridges blatantly ripped off her business ideas in an effort to get ahead.

The evidence? Rochester is claiming Bridges ripped off her, titled 5 Minute Diet Book – Bridges’s best-seller is called 5 Minutes a Day diet. She probably should’ve gone with four minutes.

In her Facebook post Rochester claims she has suffered PTSD after her experiences with Bridges.

“The reality is, I was so traumatized after the incessant bullying I received in Australia I definitely displayed symptoms of PTSD, similar to many recently reported cases of people who had been twitter shamed.

“I was scared to speak out, it took me years to find my voice and outing her on this just seems the logical step for me in facing my demons.”
