She is playing a woman who hopelessly falls for a dangerous toyboy in her latest movie.
So perhaps Jennifer Lopez was getting ready to sob for the cameras as she waited around on the set of Boy Next Door in Los Angeles on Monday.
The 44-year-old actress looked emotional as she chatted with the film's director Rob Cohen, and even wiped her face with a handkerchief as she psyched herself up for her big dramatic moment.

Ready to sob? Jennifer Lopez brandished some tissues as she got into character on the set of her new movie Boy Next Door in Los Angeles on Monday

Jennifer's cardigan was wrapped snugly around her body and served to both keep her warm and brighten her complexion as well.

Paired with a feminine pink skirt, the canny star looked like she knew exactly what she was doing as she went over the day's scenes with the filmmaker.
The saucy actress wore her hair in a casual updo with bangs parted in the middle and silky strands falling around her cheeks, which allowed a peek at her gold earrings.
Latina lovely Jennifer looked like she was listening intently as she held her tissue, which was no doubt a key prop for a scene in which her character pays a visit to her friend, played by Kristin Chenoweth.
