Jennifer Lopez and beau Casper Smart have called it quits, according to several reports out Friday.
"They initially split about six weeks ago, but that can take a little time to extricate. But they've definitely broken up," a source told People, adding, "The relationship had just run its course."
The pop star-turned-"American Idol" judge, 44, and Smart, 27, had been dating for about 2½ years, kicking off their relationship in 2011 when Smart was one of her backup dancers.
"Jennifer is actually doing really well and working hard," the mag's source added.
"It wasn't an easy decision, but they decided to stay friends," another source told Us Weekly. "Their relationship couldn't work with the distance. He started trying to establish his own life and career, and she is so focused on hers, and they just couldn't be all about each other anymore."
The pair is said to have had an amicable split and remain friendly, despite growing apart, TMZ reported.
"Casper has been a single guy and can text or see whoever he wants, but the idea that he was knowingly texting a transsexual is laughable," a source told TMZ. "He's not that guy, but like a lot of single guys online he obviously likes to look at a little ... "
The site said the former dancer is pursuing an acting career and is in the process of moving out of Lopez's house.
Meanwhile, Lopez is involved in a free summer concert series as she promotes her 10th album, "A.K.A."
Lopez, who is mom to 6-year-old twins Emme and Max, split with Marc Anthony in 2011 after eight years of marriage. She was previously engaged to Oscar-winner Ben Affleck (the original "Bennifer") and dated music mogul Sean "Diddy" Combs.
Before that, she was married twice. First to Cuban actor Ojani Noa and then briefly to choreographer Cris Judd.
The "I Luh Ya Papi" singer addressed her trail of failed romances in the April issue of InStyle.
"Look, I don't love being alone. I don't. I can't beat myself up for that. What I have to do is figure out why I don't like it. Why am I not OK being alone? And can I ever be OK facing that?" Lopez told the mag.
"In the past, love for me has always meant forever, and sure, you still nurse some of those fantasies, but I don't try to force it anymore. I hung on to my fairy-tale ideals for a long time. But where I am now, what I've been through, there are no rules."
