Elle King's husband was arrested for domestic violence prior to the couple's recently-announced split.
Ferguson was arrested April 23, a week after King announced she had "skipped out" on their wedding.
TMZ reported King and Ferguson were arguing at their Los Angeles home when Ferguson grabbed King, tossed her on a bed and threatened to kill her.
Ferguson denied the allegations, but said he threw the singer to keep her from hurting herself.
King confirmed her split from Ferguson in a post Tuesday after announcing they secretly married in March 2016.
She and Ferguson legally wed three weeks after they met, but were to tie the knot in a wedding ceremony in April.
King, the daughter of comedian Rob Schneider, has yet to address Ferguson's arrest.
