Back on? J.Lo posts pic of ex Casper Smart as her #ManCrushMonday

J.Lo has been spending plenty of quality time with her ex Casper Smart since last summer. And, there was that whole rumor about them planning a $3 million wedding that turned out not to be true, but maybe they are rekindling their romance.

We only have one piece of evidence, but it's pretty compelling. On Monday, she posted her #MCM -- aka #ManCrushMonday -- which happened to be Casper.

The photo is kinda blurry, but one thing is clear: She's feeling him ... again.
