Rosie O’Donnell Unleashes on Jay Leno After Watching ‘Biggest Loser’ Documentary: ‘Mean A–hole!’

Rosie O’Donnell has declared war on Jay Leno in a bombshell social media meltdown!

The former View co-host, 63, went off in a scathing Instagram attack after watching Netflix‘s scandalous new documentary Fit for TV: The Reality of The Biggest Loser, calling him “a mean a–hole” in a shocking post that has fans stunned.

The explosive moment that triggered O’Donnell’s rage? ​​A disturbing 2009 clip showing Leno, 75, reading death threats live on air to Biggest Loser contestant Tracey Yukich during The Tonight Show With Jay Leno. The cruel stunt, captured in the damning documentary, sent O’Donnell into a social media spiral.

But Leno wasn’t O’Donnell’s only target. The actress, who recently shed dramatic weight using Mounjaro, also savagely attacked personal trainer Bob Harper, 60, in a separate post, writing: “Can u not say IM SORRY… come on bob.” She branded his behavior on the long-running NBC series “seriously so hurtful” and “so cruel,” sharing a photo of contestant Joelle Gwynn being screamed at during Season 7.

The documentary has already triggered a legal war, with fellow trainer Jillian Michaels, 51, threatening to sue Netflix over explosive claims that she approved giving contestants caffeine pills.

Leno’s camp has remained mysteriously silent about O’Donnell’s attack.
