If there’s ever been a candidate for an anger management course, it might be Karen Elaine Harrelson.

karen-harrelsonPennsylvania State Police were called to Harrelson’s Red Lion home on Christmas Day after a call about a domestic disturbance complaint.

The alleged victim, Kayla Renee Still, reportedly ordered Harrelson not to smoke inside the home because her cousin was 7 months pregnant, the York Daily Record reports.

According to police, Harrelson became enraged, calling Still a “bitch” and threatening to “whoop her ass.”

“Still continued relating Harrelson then picked up her grandmother’s Christmas tree and approached her in an aggressive manner and threw the tree at her and that’s when they fell onto the couch,” the police report states.

Police say the two women wrestled on the couch, with Harrelson pulling Still’s hair and refusing to let go.

Harrelson was arrested and faces two counts of simple assault and one count of terroristic threats, according to the paper.

It’s not the first time Harrelson has flipped out.

In 2013, she was arrested — and ultimately plead guilty — after Harrelson and Gregory Stambaugh stabbed each other during an argument about who should win “American Idol.”

Fox 43 reports:

Stambaugh and Harrelson disagreed over whether Candice Glover or Kree Harrison should win the 12th season of American Idol.  At one point, either Stambaugh or Harrelson went to the kitchen, grabbed a knife, and stabbed the other. The victim of the first stabbing responded in kind, stabbing the stabber.

Both Stambaugh and Harrelson say the other was the first to engage in knifeplay.

Stambaugh was wounded on his forearm while Harrelson received scratches and “a laceration on the top of her wrist.”
