Constintine Maroulis, best known for his stint on American Idol, was arrested on domestic violence charges on Wednesday morning.

The mother of Maroulis’ 4-year-old daughter Malena, Angel Reed, called 911 from their Wyckoff, New Jersey home, alleging he had physically assaulted her. He was then arrested and bailed out soon after.

She accused the singer of kicking her in the groin, but he has retorted that it was an action of self defense.

Maroulis’ rep told TMZ Reed got violent with him when he tried to break up with her, even throwing something at him that hit his thigh.

He’s claiming self defense because she attacked him and he is alleging he has evidence to support the fact that it isn’t the first time she’s done so.

Gossip Cop reports Maroulis finished in sixth place on American Idol back in 2005 and he has gone on to start a solo career, act, and star in Broadway’s Rock of Ages.
