Terri Seymour had to defend herself from a crazed fan, who attempted to strangle her backstage at the singing contest in Los Angeles.
Janice Thibodeaux was taken into custody by authorities on a felony charge of battery, and she is still being held on $52,700 bail.
British TV host Seymour refused medical treatment after the incident, but remains baffled as to why she was targeted.
She tells news show Extra, "It was all very scary... She put me in a headlock and tried to choke me... Nothing like this has ever happened to me before."
Seymour had just finished covering the Idol finale for the TV show when the attack took place outside the Nokia Theatre.
She recalls, "The police were fantastic. They were close by and managed to catch her."
