'Teen Mom' Jenelle Evans and Fiancé Land in Jail After Violent Fight

"Teen Mom" star Jenelle Evans and her estranged fiancé Gary Head got into a brawl over the weekend at her Oak Island, North Carolina, home that landed them both behind bars.

Evans later tweeted, "Yes I left him becuz he was caught cheating. He did something to me that was physical and traumatizing. I'm just so grated jace wasn't there," she added, referring to her son Jace.

Evans' attorney, Dustin Sullivan, told E! Online that Evans was the one who reported a domestic violence incident on Sunday by calling 911, but police also arrested her.

Evans was charged with simple assault, possession of less than one-half ounce of marijuana, possession of a controlled substance and possession of drug paraphernalia. Meanwhile, Head was charged with assault on a female, possession of less than one-half ounce of marijuana, possession of drug paraphernalia and possession of a controlled substance.

Sullivan added that Jenelle spent Sunday night in jail and was released on a $500 secured bond while her Marine on-again, off-again partner posted a $1,500 bond.

Head later tweeted about his rocky relationship, writing, "[Jenelle is] no longer my fiancé or girl. She can be with who she pleases…I can honestly care less who she's with. And I put that on my friends grave… no. I'm def not marrying her. @PBandJenelley_1 has ruined my life."
