Jennifer Aniston and Emma Roberts, who co-starred in the film "We're The Millers," were good friends until a disturbing incident at a hotel in Montreal, Canada. In 2013, Roberts allegedly assaulted her boyfriend, Evan Peters, leaving him with a bloody nose and bite marks. Though she was arrested for domestic violence, she was released shortly afterward without being charged. Aniston disapproved of Roberts' hard-partying and public outbursts, warning her to get her act together or risk not being invited back for a possible sequel to their film. Despite Aniston's efforts, Roberts and Peters eventually called off their engagement in 2015.
