The singer was taken into custody on Wednesday morning (12Aug15) for allegedly kicking the mother of his child during an argument, but Maroulis maintains he was simply defending himself.

His ex called police from her home in Wyckoff, New Jersey, claiming the star threw her to the ground and kicked her in the groin.

Constantine's representative tells TMZ.com he was acting defensively because she attacked him. The singer is adamant he did not kick her, and claims the argument started after he told her he was leaving her, prompting the woman to throw an object at him, injuring his right thigh.
