Jennifer Aniston was upset with We're the Millers co-star Emma Roberts's behaviour. Emma was arrested for domestic violence in Montreal after a fight with her boyfriend Evan Peters.
A source said, "Jen totally disapproves of Emma's hard partying and public blowups. She has even told Emma that unless she shapes up, she may not be invited back for a possible Millers sequel".
"Jen's known Emma since she was 12. It is sad because Jen's been backing her career all the way. Jen's an old pro, and the crazy headlines about Emma and her diva behaviour just don't sit well with her".
