LOS ANGELES, Aug. 25 (UPI) -- Jennifer Lopez and Casper Smart have reportedly ended their on-again, off-again relationship after almost five years together.
"It wasn't anything dramatic and they were on good terms—it just came to a natural end. They will remain friends and they see each other, but they are not together. It was very amiable," a source close to the former couple told People magazine.
The two first broke up in 2014, but reconciled in May 2015.
A different source told TMZ the split came as the result of Smart blowing off Lopez and a Hamptons fundraiser on Saturday to spend the night at UFC 202 in Vegas.
That source also added that it's likely that Lopez and Smart could end up back together.
A rep for Lopez had no comment.
