7:38 PM PT — TMZ has obtained Tonia Haddix‘s latest mug shot from Phelps County jail … after being transferred from Camden County jail.

As you can see, the chimp lover looks a bit disheveled and down in her latest snap.

“Chimp Crazy” star Tonia Haddix — the Missouri woman who once faked her beloved chimp Tonka’s death – is back in hot water … and this time, she’s behind bars.

The 55-year-old exotic animal broker was arrested Saturday after a judge threw her in jail for dodging court orders to cough up $224k in legal fees owed to PETA. But get this … when officials raided her home, they found another hidden chimpanzee living in her basement.

In court docs obtained by Rolling Stone, authorities say Haddix was secretly stashing a “mature female chimp” in a makeshift enclosure, complete with blankets, a Gatorade bottle, and half-eaten candy. They safely removed the ape during a surprise search earlier this month.

This all comes years after Haddix pulled a wild stunt, faking Tonka’s death to stop him from being taken to a sanctuary. He was later found alive.

Haddix’s husband, who allegedly tried to stall officers during a home visit, is also facing arrest.
