Chapman's husband, bail bondsman Duane "Dog" Chapman, confirmed early Sunday that his wife had been admitted to the ICU at Queen's Medical Center in Honolulu.
Chapman starred with her husband on the A&E reality show "Dog the Bounty Hunter," which ran from 2004 to 2012. The show followed Dog, the mulleted bounty hunter, and his platinum blond wife Beth, who formed a ferocious team that tracked down bail fugitives and filmed in Hawaii as well as Colorado.
In September 2017, the couple used their Facebook account to announce Beth Chapman had been diagnosed with Stage 2 throat cancer.
They revealed during an A&E special "Dog & Beth: Fight of Their Lives" in November 2017 that the cancer had been removed, but it came back last year. She was hospitalized in April due to an accumulation of fluid in her lungs, and doctors performed an emergency procedure to alleviate pressure, the couple said at the time.
TMZ reported Tuesday that Beth Chapman's mother had flown to Hawaii to be with her at the hospital.
