Jessica Simpson‘s startling new look has come at a heavy cost according to sources close to the spiraling songbird, RadarOnline.com can reveal.

Insiders said the trout-pouted pop star is unraveling over the shaky state of her 10-year marriage to retired football pro Eric Johnson and her dormant singing career.

The damning double-whammy is said to be fueling the 44-year-old’s soaring insecurities and pushing her to dangerous dieting and a slew of cosmetic surgeries.

“Up close, she looks unwell,” an insider said. “To be honest, Jessica hasn’t been herself for a long time.”

Horrified fans are shocked by unrecognizable Jessica’s jaw-dropping transformation.

Many of her fans griped about her altered appearance on social media – with one comparing her to plastic-faced Kim Zolciak of The Real Housewives of Atlanta.

A follower commented: “Whoa. You don’t look like Jessica.” Another wrote: “Girl! Who is this??”
