If Casper Smart isn't sweet, he won't last long in Jennifer Lopez's world.
Amid rumors that Lopez, 43, and Smart, her 25-year-old boy-toy, are on the rocks, the pop star talks love in the September issue of InStyle magazine.
"The most important quality the man in my life should have is that he is sweet. I like the good guys," the former "American Idol" judge told the magazine, which she covers. "The hard part is that you never stop believing in love. You never stop. But that's also the best part. You never stop believing, and you never, ever give up."
Lopez and Smart - who met because Smart was Lopez's backup dancer - started dating in the fall.
