A beautician from Puerto Rico testified yesterday that she “wanted to die” after munching on a lizard served up as part of an in-flight chicken dinner.

Monserrate Luna said she absentmindedly popped the creepy crawler into her mouth while watching a movie onboard an American Airlines flight from JFK to San Juan in 2003.

After chewing for a while, she was unable to swallow the mystery meat and spit it into a napkin. Her 5-year-old son confirmed, it was “an animal,’ ” she testified in Manhattan federal court.

Airline lawyer Kenneth Gormley claims the masticated mess was chicken skin, and that “there may have been some feathers, or what looked like feathers . . . but there was no lizard.”
