The film, directed by Rob Cohen, tells the story of a woman's torrid relationship with her neighbor (Ryan Guzman). But the plot goes from sexy to scary when the man develops an obsession with Lopez's character.

The erotic thriller marks the 45-year-old singer's return to cinema since the 2003 flick "Parker." Lopez is scheduled to appear in a number of movies next year, including "Lila & Eve" and the animated film "Home."

Also starring Kristin Chenoweth and John Corbett, "The Boy Next Door" hits theaters on Jan. 23, 2015.
