Well, we all saw this coming.
There are rumors that their breakup involved sexting a transgender bikini model, though sources say the Love Don't Cost a Thing lady spent weeks going "back and forth" about whether to raise the white flag on their relationship!
Regardless of what prompted the split, her 27-year-old ex might actually be in a better place now!
According to those close to Casper, he is focused on launching his acting career.
".. Casper is focused on acting and going on auditions and Jen has completely supported that… He is trying really hard to launch his acting career. He doesn't want to be known as just her boyfriend."
Well, you got your wish, buck-o! Now you're known as J.Lo's ex-boyfriend!
But maybe soon you'll be known as an A-list movie star!
Hopefully your newly single status allows you to land some super-sweet movie roles!
