Hello boys! JLo is movin' in the neighborhood!

Wearing a geometric design by David Koma, Jennifer Lopez sizzled at the premiere of her sexy new film, The Boy Next Door, hosted by BodyLab in Miami.

In the film, Jennifer stars as recently divorced high school teacher who has a passionate one-night stand with her new, much younger neighbor (Ryan Guzman). Unfortunately, the pretty young thing turns out to be a student. Eventually, the ill-fated fling turns into a dangerous obsession.

And its possible that Jenny from the block has lit more than the silver screen on fire with her relationship with Guzman. The two seemed pretty chummy at a Golden Globes after party on Sunday, sparking the rumors that the 45-year-old and the 27-year-old were more than just costars.

The film moves into theaters on January 23.
