It appears another Hollywood A-list couple may be calling it quits. Multiple reports are claiming that singer and 44-year-old actress Jennifer Lopez and her 26-year-old backup dancer boyfriend, Casper Smart, are headed for splitsville.

According to a report from E! News Tuesday, the couple, who started dating in Nov. 2011 before Lopez officially divorced husband Marc Anthony in 2012, have been arguing non-stop and have considered ending their relationship of two years. “Things are not going well at the moment,” an insider revealed, adding, “They are bickering, and it’s clear to the people around them that there is an irritation between them at the moment. It’s hot and cold, but more cold than hot right now.”

While the couple has yet to confirm or deny the reports, Star magazine reported Tuesday that the twosome is officially on the outs. According to the magazine’s claims, the pair had a “blowout fight” earlier this month, which led to the split. The cause of the argument? Allegedly, it was the couple’s continuing issues related to jealousy. “She threw him out,” a source said, adding, “She didn’t get her away about something and blamed him.”

According to a report from RadarOnline Monday, the couple was last spotted together three weeks ago, an unusually long time out of the spotlight for the reguarily public twosome. “Jennifer is pretty private about the relationship, but she’s been hinting that the spark is gone,” said a source following Lopez’s appearance at the Human Rights Campaign national dinner in Washington, D.C., on Oct. 5, which Smart did not attend. “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. “She enjoyed the relationship for what it is, but now that giddiness has turned to sadness.”

While Lopez and Smart may be plagued with jealousy issues, a report from E! News in July 2011 indicated that Lopez also split from Anthony, the father of her five-year-old twins Max and Emme, for the same reason. According to the report, the couple dealt with issues of jealousy early on in their marriage, and while a source claimed the “My Baby You" singer was “controlling,” the source noted that the insecurities in their relationship “cut both ways.”

Lopez can next be seen reprising her role as a judge on the FOX reality singing competition series, “American Idol." The 13th season of the show is scheduled to premiere in January 2014.
