Wearing a tight fitting mustard-coloured turtle-neck sweater and a pair of faded denim jeans, the 44-year-old actress appeared on set looking fit and lovely as she prepared to film a scene from the Universal film.
The outfit highlighted the former American Idol judge's famous curves, an attribute that gave her the nickname 'La Guitarra' in her younger days.
Her flawless make-up made the screen siren glow with good health as her perfectly coiffed hair did little to make her look like a typical neighbourhood mother.
In feature, Jennifer Lopez plays a divorced mother who begins an ill-advised affair with an unstable teenage neighbour.
After she attempts to break off the affair, she becomes the object of obsession for the young man as his fixation takes a dangerous turn.
The Rob Cohen-directed film co-stars Kristin Chenoweth and John Corbett and is produced by Blumhouse Productions, best known as the production house behind the horror hits Insidious and Paranormal Activity.
The Boy Next Door is set as a 2014 release.
