Are Jennifer Lopez & Casper Smart Headed For a Break Up?

Jennifer Lopez and her dancer boyfriend Casper Smart have made headlines since their romance began last November. From comments about his age to issues with her kids to gay rumors, Jennifer and Casper have pretty much heard it all throughout their nine months together. But now it seems like J. Lo could be tiring of her relationship with the 25-year-old.

A source has told People that Jennifer is "getting frustrated with him" and that she's become increasingly "short-tempered when she's around him." In the past, one source close to the couple referred to their relationship as just "a fun fling." If this is the case, Jennifer could be preparing herself to move on.

Casper is currently touring the globe with Jennifer and Enrique Iglesias, so a break up may not occur as soon as some might think. "Jennifer is the kind of girl who doesn't like to be alone," says the source. "Until she finds a replacement, I think, he's around."

What do you think is going to happen with Jennifer and Casper? Do you think she's going to leave him sooner rather than later?
