KNOCKING HER BLOCK OFF!

Tinseltown turns on tacky J.Lo

EGOMANIAC Jennifer Lopez is in a tizzy as sources tattle her carefully crafted image is crumbling and she's turning into the most hated gal in Hollywood!

Sources snitch Ben Affleck's 54-year-old bride's reputation is in tatters in the wake of recent image-shredding events including:

• Her failed $20 million album and documentary, This Is Me.
• Phony stories about her girlhood in the Bronx.
• Her close association with accused sex creep Sean "Diddy" Combs.
• Claims she made moves on Ryan Guzman, her co-star in the 2015 movie The Boy Next Door, even though he had a girlfriend.

Dishes an insider, "Jennifer's fall from grace has been coming for a while and it's really all her fault because she's the one driving it.

"She lives in a world of make-believe and people aren't buying the act anymore. 

They're labeling her a phony and narcissist and someone who's tone-deaf to the real world around her.
