Actress Emma Roberts was arrested last week on domestic violence charges in Canada.

The 22-year-old niece of Julia Roberts was taken into custody after she got into an altercation with her boyfriend, “American Horror Story” star Evan Peters, according to TMZ and MTV News.

TMZ reports that Roberts was arrested after someone called the cops to report a fight in the couple’s Montreal hotel room.

Peters, 26, reportedly had a bloody nose and a bite mark when police arrived, so they arrested Roberts on the spot. They released her hours later because Peters elected not to press charges, according to MTV News.

In a joint statement, the two young actors reps addressed the incident.

"It was an unfortunate incident and misunderstanding. Ms. Roberts was released after questioning and the couple are working together to move past it," the reps told Us Weekly.

Peters and Roberts appeared in the dark comedy “Adult World,” which was shown at this year’s Tribeca Film Festival.
