CHICAGO FIRE HUNK'S TRAGIC BURNOUT BARED

CHICAGO FIRE hunk Taylor Kinney took a leave of absence for “a personal matter” back in January, but sources say the missing 41-year-old star actually broke down from his grueling work ways and flamed out!

“He was pushing himself way too hard with dangerous stunts and 18-hour days on set,” spills a spy. 

On Jan. 20, a production source said Kinney, a mainstay of the NBC hit for a decade, was stepping away.
