Jennifer Lopez and her young boyfriend, Casper Smart, may be on their way to a breakup.

Jennifer Lopez and her boy toy, Beau 'Casper' Smart, may be headed for splitsville after reports revealed there may be trouble in paradise.

Rumors that Lopez and Smart may not be an item for long swirled around when the pair did not pose together for photos at a recent event. Before accepting her Ally for Equality Award at the Human Rights Campaign national dinner, Lopez took pictures with several guests on the red carpet, but Smart was nowhere to be seen.

While the 25-year-old backup dancer attended the event with Lopez, he did not appear with her and stood behind the scenes throughout the evening. The pair hasn't actually been photographed together since Sept. 21, and it has raised speculation that they could be breaking up soon.

"Jennifer is pretty private about the relationship, but she's been hinting that the spark is gone," a insider said. "She's having a hard time ignoring the fact that her head has been telling her for a while that this thing with Casper isn't forever. And now her heart's saying the same thing."

The source added that Lopez wants to be more responsible and avoid making past mistakes again. "She enjoyed the relationship for what it is, but now that giddiness has turned to sadness."

Apparently, the 44-year-old mother of twins has tried to break things off with Smart a few times already. However, she always takes him back. According to the source, Lopez has a hard time letting go of Smart because of his close relationship with her two small children, Elle and Max.

"It's hard for her to think of how to explain it to the twins," added the source. "They love Casper. Jennifer's probably going to at least stay friends with him, so hopefully it won't be as dramatic as it's been talking to them about her split from their dad [Mark Anthony]."

Lopez recently told Cosmopolitan magazine that she brings "a lot to the table" when it comes to romantic relationships. She also hinted that Smart may not be up to par as to what she expects in a man.

"It's funny, early on with Beau [Casper], I remember telling him how I have a real button on being ignored. And he was like, 'Listen, if somebody ignores you, then forget them. They don't deserve to have your attention.'" Lopez told the magazine. "But it's funny. Sometimes when we don't get it, we try to get it in a negative way, you know?"
