Julia Roberts' actress niece Emma was arrested in Montreal, Canada last week (07Jul13) after allegedly attacking her boyfriend.

The 22 year old, whose father is Julia's brother Eric, was taken into custody after police responded to reports of a fight between her and actor beau Evan Peters in a city hotel and found him with a bloodied nose, according to Tmz.com.

Roberts was released hours later because her 26-year-old boyfriend did not want to press charges.

The couple has not split and are currently working together on Tv drama American Horror Story.
