It does not look like Casper Smart will be Jennifer Lopez's next husband. Multiple reports claim the pair has split after two and a half years of dating.

"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. "The relationship had just run its course."

They added, "Jennifer is actually doing really well and working hard." 

Lopez hooked up with Smart, who worked as her backup dancer, in 2011 following her split from husband Marc Anthony. She praised Smart for being great with her twins Max and Emme and for helping her with her career.

"I'm one of those people who does not like to be alone," the "Dance Again" singer admitted in January. "I have no shame saying that at this point in my life. I think we have to own who we are."

However, she was hesitant about walking down the aisle a fourth time.

"I don't know, I don't know, we'll see," Lopez said. "I always believed in that institution. My parents were married for a very long time, for 35 years. I believe in it. It's difficult. I've had my challenges but at the same time I believe in love. That's the main thing."

This comes on the heels of claims that Smart was exchanging pictures and sexy messages with transsexual model Sofie Vissa. He took to Instagram to blast these rumors, calling them nasty.

"(It's) sad what the media does to people...Along with this nasty story. Thanks. Could you imagine if people came at you, your wife, your kids daily," the dancer wrote.

We are so sad to hear this news! Do you think Vissa got in the way, or did the relationship just run its course? Let us know your thoughts in the comments section below.
