According to the National Enquirer, J-Lo boy toy Casper Smart is "terrified" that she's getting a little too friendly with actor-model Ryan Guzman -- who plays her teenage boyfriend in the upcoming movie The Boy Next Door. A source tells the paper that Casper, who met Jennifer when he landed a gig as one of her backup dancers, “knows better than anyone that Jen has a weakness for handsome young men she works with. Casper runs her errands, grocery shops, picks her kids up from school and prepares meals at home –- [but he] doesn’t think he stands a chance once Jen and Ryan start filming their red-hot love scenes.”

For those keeping score at home, both boys are 26 years old -- that's 18 years younger than La Lopez.
