22-year-old Emma Roberts was taken into custody by Montreal police on July 7 after someone called the police to report a fight in Emma and Evan's hotel room. When police arrived on the scene, Evan had a bloody nose and a bite mark, so she was arrested.

The actress was released hours later because Peters did not want to press charges.

The two were said to be hitting each other and Roberts was arrested because Peters had obvious physical injuries, a source told the website. A law enforcement source said Peters also had a bite mark, but a source close to Roberts denied the Valentine's Day actress bit him.

The couple are now reportedly back together and are working on Peters' hit show American Horror Story. She met Peter last year on the set of Adult World and have been spotted in public displays of affection since becoming a couple. The two attended a Halloween party in Beverly Hills last October and were holding hands as Roberts was dressed in the same iconic outfit her famous aunt wore in the opening scenes of 1990's Pretty Woman.

They also joined other celebrities in April at the Coachella Valley Music and Arts Festival in Indio. In May, they kissed while waiting in line to buy tickets at the Metropolitan Museum of Art in New York City. Peters has called the Nancy Drew star 'the love of my life' and stars in FX's hit horror show while his girlfriend has a recurring role.

Emma is the daughter of Eric Roberts, an actor best known for his work in 1985's Runaway Train and his troubles with drug abuse. He was arrested in 1987 for possession of cocaine and marijuana and in 2011 appeared in Celebrity Rehab for his dependency on medical marijuana. He was estranged for years from his famous sister Julia but they have since reconciled.

Emma will next be seen in We're the Millers - due out August 7 - alongside Jennifer Aniston, Jason Sudeikis, and Ed Helms. In the dark comedy Emma plays Julia, a 'disturbed 20-year-old runaway' who poses as Sudeikis and Aniston's daughter amidst their plan to ferry 1,400 pounds of marijuana from Mexico to the US.
