2014 MTV Video Music Awards - Arrivals
Jennifer Lopez is still sexy at 45 to make any boy hot for teach.

The sexy singer returns to the big screen in "The Boy Next Door," and the first trailer shows that Lopez still has "it." She plays a high school teacher and divorced mom who becomes involved with an underage student who moves in next door (Ryan Guzman, "Step Up").

After a steamy night together, Lopez comes to her senses, but Noah becomes obsessed with her - joining her class, befriending her son, and plastering her classroom with pictures of their encounter.

"I'm never letting you go," he says ominously.

Lopez's film career has been sputtering in recent years. Last year's Jason Statham vehicle, "Parker," bombed, as did her last starring vehicle, 2010's "The Back-Up Plan." So, can she return to her more critically-acclaimed, hit days with "The Boy Next Door." We'll see when the thriller hits theaters Jan. 23, 2015.
