The green-eyed monster of jealousy erupted into the orange flames of fire as a woman in eastern Pa. admitted in court to setting fire to her unfaithful girlfriend.

As the Morning Call of Allentown reports, Kayla L. Mettler, 28, of Pen Argyl, Pa., pleaded guilty Thursday to felonies of aggravated assault and risking a catastrophe, admitting to setting her girlfriend on fire because she was "very upset."

Believing her girlfriend was involved with someone else, Mettler sprayed lighter fluid on Brittany Hoey, her girlfriend of five years, then threw a match last October.

Hoey suffered second-degree burns to her left ear, arms and chest.

Under her sentence by a Northampton County judge, Mettler will serve two to four years in state prison, the Morning Call reports.

However, it could have been much longer, but for her plea and the fact that Hoey and her family were OK with the sentence:

Lisa Hoey, Brittany's mother, is quoted by the Morning Call saying this in court to Mettler:

"It may be a sentence, but it is an opportunity -- to do what you need to do, take care of what you need to take care of."

Both women were overcome with emotion.
