Jennifer Lopez And Casper Smart Look Happier Than Ever!

Despite rumors of a possible end to their year-long relationship, Jennifer Lopez and her much younger main squeeze, Casper Smart, was the picture of happiness as they strolled through the park on Sunday.

Smart looked relaxed in cut-off jeans, and a white T-shirt while carrying 4-year-old Emme, and Lopez wore a summery blue-white sundress with her hair knotted in a messy bun.

"Enjoying the beautiful day with my coconuts at the park!! #dayoff #familia #LOVE," Lopez later tweeted.

Various media outlets have reported that Lopez and Smart are on the brink of a breakup.

She's getting frustrated with him" and she's increasingly "short-tempered when she's around him." People magazine reported of the couple just last week.

They have not split yet, but it's fair to say they are cooling off a bit. A source told E! News. "Jennifer cares about Casper, they are certainly very close," the source added. "But he is not the love of her life. She can live without him. If she does decide to split from him she'll be ok. She just needs some time to think about whether Casper is worth all this trouble."

If there is indeed trouble in paradise, the couple are doing a heck of a job hiding it. 

Lopez is an eternal optimist when it comes to matters of the heart. "I'm a hopeless romantic and passionate person when it comes to love," Lopez explained to Vanity Fair after ending her marriage to singer, Marc Anthony. But, the former "American Idol" Judge seems to have evolved into a much wiser woman due to the mistakes she made in her failed relationships.

"It's not that I didn't love myself before. Sometimes we don't realize that we are compromising ourselves." said Lopez. "To understand that a person is not good for you, or that that person is not treating you in the right way, or that he is not doing the right thing for himself-if I stay, then I am not doing the right thing for me. I love myself enough to walk away from that now."
