Universal has released its 'The Boy Next Door' trailer, proving once again that 45-year-old Jennifer Lopez is still one hot tamale. We've seen her steam up our computer screens with that music video for "I Luh Yah Papi," in which she manhandled all her numerous boy toys, but now she's in way too deep with her smokin' hot but super-underage next-door neighbor.

Most people have one-night stands and then move on with their lives, but when it's J. Lo and that constantly shirtless stud from the 'Step Up' movies, Ryan Guzman, enough is never enough (get it?! She starred in that movie 'Enough'?). From the 'Boy Next Door' trailer, we know that she'll be getting all 'Desperate Housewife'-y with, yes, the boy next door, an attractive high school guy who takes advantage of her depressing home life and seduces her. (When Aidan from 'Sex and the City' is your husband, you're bound to have a depressing home life.) But she'll soon realize that you just can't sleep around with "crazy."

Sure, 'The Boy Next Door' has a Tyler-Perry-movie vibe to it, but no sex can resist the charms of J. Lo (especially since that teaser for the "Booty" remix came out) coupled with the dancer abs of Guzman.

'The Boy Next Door' will hit theaters on January 23, 2015.
