Jennifer Lopez and Casper Smart did NOT get back together, because we found out they were never really apart.

Sources close to the couple tell us … the break-up they announced in June was a business move. Multiple sources say in the spring they did stop seeing each other, but only for a few weeks.

We’re told JLo was hawking her movie, “Boy Next Door,” and honchos on the film felt creating a buzz that she was hooking up with co-star Ryan Guzman would help sell tickets. It’s hard to do that when you’re not single.

But the decision wasn’t one-sided. We’re told Casper was up to the same thing because he was shooting “Street,” a UFC fighter movie where he buffed up. Again, he was more appealing single.

It all makes sense now. Two months after they revealed their break-up, a photog got shots of them in a convertible BMW. When JLo saw the photog, Casper put the top up and she slumped down in the passenger seat, out of sight.

Then in December, a dog at Jennifer’s house bit a neighbor. Turns out it was Casper’s dog that did the deed and he came running out of the house in his pajama bottoms after the attack.

In February, Casper went to a GQ event, and when he left he walked down the block and jumped in a car JLo was driving, avoiding photogs. A few minutes later a photog saw them walk into a restaurant together. When they saw the guy they hightailed it inside.

And then they got bolder, dancing together at a Big Sean concert at the House of Blues in WeHo.

Case closed.
